DA ACOUSTIC REPORT

1 Introduction

Renzo Tonin & Associates was engaged to undertake an operational noise assessment to support the

Development Application (DA) for the proposed place of worship (mosque) and community centre,

located at 88-90 and 92 Botany Street, Carlton.

The development is proposed to have a maximum 120-patron capacity and 22 car spaces located on

site. The proposed operational hours are from 5:30am to 9:55pm (Monday to Sunday).

However, it should be noted that the effective usage hours of the mosque for prayers are as follows

(except month of Ramadan) - Monday, Tuesday, Wednesday, Thursday, Saturday and Sunday – 1.5

hours per day and on Fridays – 2 hours per day.

A patronage size of 100 will only occur once per week (Friday midday prayer) with other prayer services

attracting a maximum of 20 people.

Up to 10 times per year, (typically expected to be public holidays that fall on a Friday, and first two and

last two days of Ramadan), a maximum capacity of 120 is expected.

The primary aspect of noise emission will be from on-site vehicle movements and carparking, breakout

noise from internal areas and traffic generated on the public road system.

The report quantifies noise emission from activities associated with the development and assesses

operational noise on nearby sensitive receivers in accordance with the noise requirements of the NSW

Noise Policy for Industry (NPfI) and the NSW Road Noise Policy (RNP). These potential noise generating

activities relate only to the mosque’s prayer sessions which are limited to 1.5 hours per day and 2 hours

on Fridays, with the exception of Ramadan.

The work documented in this report was carried out in accordance with the Renzo Tonin & Associates

Quality Assurance System, which is based on Australian Standard / NZS ISO 9001. APPENDIX A contains

a glossary of acoustic terms used in this report.

2.2.1 Discussion regarding prayer time

It should be noted that Ramadan prayers that commence late are those that happen to fall over the

longest daylight days in summer and are cyclical and only take place with reference to the lunar

calendar cycle. The late prayer sessions for Ramadan month also don’t always cover the full month

period either (see explanation below). This means that this acoustic/noise report has assessed the

ultimate worst case scenario but the frequency that these occur is irregular but dictated by a 33 year

cycle.

The Muslim calendar is based on the Lunar calendar rather than the Gregorian calendar. The points

below and the Ramadan Cycle diagram in Figure 1, help to explain this.

a) The Muslim calendar is 10-12 days shorter than the Gregorian calendar.

b) Ramadan therefore commences earlier each year until it progressively returns back to the

start of the cycle every 33 years.

c) Ramadan prayer sessions follow sunsets of whichever season they fall onto.


NASSCON PTY LTD


DA ACOUSTIC REPORT

d) Ramadan prayers commence the latest (in the day) when Ramadan falls over the longest days

of a summer season (19 December to 26 January), where the sunset is so late that it occurs

between 8-8:10pm.

e) In these scenarios, Ramadan can span up to 1 month in duration (though most adjacent

years are less, see below) and take place each year for 5 years of the 33 year cycle.

f) In accordance with Islamic practices, a minimum 1 hour time is necessary before evening

prayer can commence equating to a 9:10pm commencement time for prayers.

g) The next time a scenario where Ramadan will occur return to a cycle that affects the longest

days of the summer seasons in the year of 2029.

h) For the remaining 28 years in the 33 year cycle, all other Ramadan commencement times will

be commensurately earlier and align with sunsets of the relevant season.

i) The next time these late Ramadan prayer sessions will occur will be in 2029:

• In 2029 – 11 days

• In 2030 – 21 days

• In 2031 – 29-30 days

• In 2032 – 22 days

• In 2033 – 15 days

• From 2034 and ongoing – nil (until next cycle)

Renzo Tonin & Associates has assessed the worst case scenario where acoustic and noise impacts occur

later in the evening for reasons stated above. The above explanation also provides an accord of how the

month of Ramadan is affected by the Lunar calendar through its natural shifts and cycles. It shows that

over the 33 year cycle, only over 5 years would Ramadan have a commencement time of 9:10pm and

they would all complete by 9:45pm. Over this 5 year span, only in the year of 2031 would span the full

Ramadan month with years 2031 and 2032 spanning over 21 and 22 days, respectively. For years 2029

and 2033 Ramadan would only affect 11 and 15 days out of the full month, respectively.

2.3 Acoustic aspects

Based on the proposed design and operational parameters, the following aspects are deemed to require

acoustic assessment:

• On-site vehicle movements and carparking

• Breakout noise from internal areas

• Patrons external to the building

• Traffic noise on public roads

• Mechanical services plant and equipment noise


NASSCON PTY LTD


DA ACOUSTIC REPORT

2.4 Acoustic assessment methodology

In order to assess the potential noise impact from the development the following methodology was

used:

• Identify nearest most potentially affected receiver locations to the subject site

• Determine existing background noise levels at the nearest most potentially affected receiver

locations

• Use measured background noise levels to establish noise goals in accordance with the

relevant noise criteria

• Using predictive noise modelling, determine the extent of noise impacts from the proposal at

potentially affected receiver locations

• Identify if noise emission from the area under investigation may exceed the relevant noise

criteria (outlined in Section 0), and

• Where noise emission from the area under investigation may exceed the relevant noise

criteria (outlined in Section 0), provide recommendations to reduce noise impacts from the

site.

2.6 Assessment locations

The identified assessment locations are outlined in Table 5 below and are shown in Figure 3.

The assessment height that has been adopted is 1.5 metre above ground level for ground floor, plus 3.0

metres for additional floors. R3 is a single level dwelling but is elevated along the western facade so an

assessment height of 4.0 metres above ground level has been used. For each individual receiver, the

ground level assessment has been made at the nearest / worst affected location within the property and

the upper-level assessment has been made at the nearest / worst affected window/balcony.

3 Existing noise environment

Criteria for the assessment of operational noise are usually derived from the existing noise environment

of an area, excluding noise from the subject development.

Fact Sheet B of the NSW EPA Noise Policy for Industry (NPfI) outlines two methods for determining the

background noise level of an area, being ‘B1 - Determining background noise using long-term noise

measurements’ and ‘B2 - Determining background noise using short-term noise measurements’. This

assessment has used a combination of long-term and short-term noise monitoring to further improve

the rigour of assessment.

As the noise environment of an area almost always varies over time, background and ambient noise

levels need to be determined for the operational times of the proposed development. For example, in a

suburban or urban area the noise environment is typically at its minimum at 3:00am in the morning and

at its maximum during the morning and afternoon traffic peak hours. The NPfI outlines the following

standard time periods over which the background and ambient noise levels are to be determined:

• Day: 07:00-18:00 Monday to Saturday and 08:00-18:00 Sundays & Public Holidays

• Evening: 18:00-22:00 Monday to Sunday & Public Holidays

• Night: 22:00-07:00 Monday to Saturday and 22:00-08:00 Sundays & Public Holidays

The NPfI also outlines methods for assessing 'shoulder periods' being shorter periods on either side of a

standard period, where the standard period noise levels are not representative. For example a 'shoulder

period' may be warranted for 05:00-07:00 where the night time period background noise level is not

representative. Fact Sheet A, Section A3 of the NPfI outlines two suitable methods to determine the

shoulder period background noise level.

3.1 Noise measurement locations

Noise measurements are ideally carried out at the nearest or most potentially affected locations

surrounding a site. In circumstances where there may be restrictions on access or the unavailability of

safe and secure locations to establish monitoring equipment, then a suitable alternative location should

be established. These are known as representative locations. Furthermore, representative locations may

be established where multiple receivers have been identified, as it is usually impractical to carry out

measurements at all locations surrounding a site.

The long-term and short-term measurement locations are outlined in Table 6 and shown in Figure 3 and

APPENDIX B. Photos are provided in APPENDIX B for clarity. These measurement locations are

considered conservative as the locations are located at the rear of the property with significant shielding

from Botany Street. Whereas the most sensitive assessment points (i.e. windows) of the surrounding

residences are elevated (4m and greater above the ground) and have more exposure to Botany Street.

The effect is that some receiver locations (particularly R1 and R4) would most likely have higher criteria

than what has been adopted.


NASSCON PTY LTD


DA ACOUSTIC REPORT

At the time of the measurements in 2019 and 2021, the existing development at 88-90 Botany Street,

Carlton (Botany Gardens Nursing Home) was permanently closed. The facility was vacant, and no

mechanical plant from the site was operating.

Multiple attempts were made to engage with residential locations, 84 Botany Street, Carlton; 86 Botany

Street, Carlton; and 27 Xenia Avenue, Carlton to utilise their backyards for long term noise monitoring

but were unsuccessful. Renzo Tonin & Associates testing methodology has been undertaken to address

this constraint, with short term monitoring undertaken again to test consistency.

Table 6: Noise monitoring locations

ID Address Description

Long-term noise monitoring

L1 88-90 Botany Street, Carlton

Southern boundary

The monitor was located at the facade (1 metre from the southern boundary

fence) along the southern boundary of the site.

The noise monitoring location is considered representative of receiver locations

R1 and R2.


Eastern boundary

The monitor was located in the free field (greater than 3.5 metres from reflective

surfaces) near the eastern boundary of the site.


R3 and R4.


First floor facing Xenia Ave

The monitor was located in the free field (greater than 3.5 metres from the

facade and other reflective surfaces), protruding out of the first-floor window

facing Xenia Ave.


R1 and R2. The monitoring was undertaken to supplement monitoring location

L1.


First floor facing Botany Street

The monitor was located at the facade (2 metres from the facade), protruding

out of the first-floor window facing Botany Street. An awning was prohibiting the

monitor to be place 1 metre from the façade, see APPENDIX B for photo.

The monitor was located 10 metres from the edge of the southbound ‘drivable’

lane of Botany Street (note Botany Street has a lane of parking either side of the

street). The noise monitoring location is considered representative of the nearest

receivers to Botany Street traffic. The monitoring was undertaken to determine

existing traffic noise levels from Botany Street.

Short-term noise monitoring

S1 88-90 Botany Street, Carlton

Southern boundary

The monitor was located at the same position as monitoring Location L1. That is,

at the façade (1 metre from the southern boundary fence) along the southern

boundary of the site.

The monitoring was undertaken simultaneously with monitoring location S2 for

a duration of 3 hours. The monitoring was undertaken to determine if reflective

surfaces have any effect on the captured background noise level (LA90), to justify

why facade corrections are not applicable to the LA90 descriptor and why a 2.5dB

adjustment is not required for monitoring location L1.


Southeast carpark

The monitor was located in the free field (greater than 3 metres from reflective

surfaces) towards the centre of the southeast carpark.

The monitoring was undertaken simultaneously with monitoring location S1 for

a duration of 3 hours. The monitoring was undertaken to determine if reflective

surfaces have any effect on the captured background noise level (LA90), to justify

why facade corrections are not applicable to the LA90 descriptor and why a 2.5dB

adjustment is not required for monitoring location L1.

ID Address Description

S3 92 Botany Street, Carlton The monitor was located 10 metres from the edge of the southbound ‘drivable’

lane of Botany Street (note Botany Street has a lane of parking either side of the

Monitoring was undertaken to determine sound power levels from car pass-bys.


The monitor was located adjacent to the existing driveway associated with the

southwest carpark. Several simulations were undertaken by Renzo Tonin and

Associates driving in and out of the carpark.

Monitoring was undertaken to determine sound power levels from cars entering

3.2 Short-term noise measurement results

3.2.1 Site background noise levels

Outline of methodology and description of technique

Short-term noise measurements were undertaken during the daytime of Wednesday, 26 May 2021 in

order to supplement the long-term noise monitoring. Furthermore, the 3 hour short term noise

measurements were undertaken to determine if reflective surfaces have any effect on the previously

captured background noise level (LA90) and justify why facade corrections are not applicable to the LA90

descriptor and why a 2.5dB adjustment is not required for monitoring location L1.

The equipment used for noise measurements was an RTA Technology RTA06 noise logger which is based

on an NTi Audio Type XL2 precision sound level analyser which is a class 1 instrument having accuracy

suitable for field and laboratory use. The instrument was calibrated prior and subsequent to

measurements using a Bruel & Kjaer Type 4231 calibrator. No significant drift in calibration was

observed. All instrumentation complies with IEC 61672 (parts 1-3) 'Electroacoustics - Sound Level Meters'

and IEC 60942 'Electroacoustics - Sound calibrators' and carries current NATA certification (or if less than

2 years old, manufacturers certification).

The recording time of the equipment, on both loggers, was set to be exactly the same so that a direct

comparison of results could be made. During observations throughout the measurement, the ambient

LAeq noise level was determined by local traffic and the background LA90 was determined by school

(Sydney Technical High School), neighbourhood noise and distant traffic.

Results/findings

A summary of the short-term measurement results is presented in Table 7. The data confirms that the

difference in background LA90 noise level is insignificant. In summary, earlier background noise

monitoring has been demonstrated to be consistent and accurate with any new methodology proposed

by others.

Outline of methodology and description of technique

Attended noise monitoring was undertaken during the daytime of Wednesday 26 May 2021, on the

front lawn of 92 Botany Street (monitoring location S3) in order to determine car pass-by sound power

levels for cars travelling at the posted 50km/hr speed limit.

Attended noise monitoring was undertaken during the daytime of Wednesday 26 May 2021, adjacent to

the driveway of the south-west carpark at 88-90 Botany Street (monitoring location S4) in order to

determine sound power levels for cars entering and leaving the site.

The equipment used for noise measurements included an NTi Audio Type XL2 precision sound level

analysers is a Class 1 instruments having accuracy suitable for field and laboratory use. The instrument

was field checked for calibration prior and subsequent to measurements using a Bruel & Kjaer Type

4231 calibrator. No significant drift in calibration was observed. All instrumentation complies with IEC

61672 (parts 1-3) 'Electroacoustics - Sound Level Meters' and IEC 60942 'Electroacoustics - Sound

Measurement of Environmental Noise

Australian Standard 1055-2018 Acoustics – Description and Measurement of Environmental Noise

(AS1055) sets out procedures for the description and measurement of environmental noise.

Section 6.2.3 of AS1055 specifies:


NASSCON PTY LTD


DA ACOUSTIC REPORT

6.2.3 Outdoor measurements near buildings

Outdoor measurements near a building shall be carried out at places where the noise to which the

building is exposed is of interest. Except when determining LA90,T, an adjustment may be necessary

where an approximation of the free field incident level is required. See Note 3.

NOTES:

1 The measurement positions should be 1 m from the facade and 1.2 m to 1.5 m above

each floor level of interest. An adjustment may be necessary where an approximation of

the free field incident level is required to account for the influence of facade reflections

(see Note 2). Where measurements are made at different levels of a multi-storey building

such as an apartment block, the location should be 1 m from the facade of the building

separating the external area from the interior area.

2 Where measurements are made near a building the importance of certain transmission

paths (for example, transmission through open or closed doors and windows) should be

considered.

3 If measurements are performed 1 m from the facade of a building and the sound is

directly incident on that facade, an approximation of the free-field incident level may

be obtained by subtracting 2.5 dB from the measured value. To characterize the effects of

the walls of a building to be erected, the addition of 2.5 dB to the free-field values may be

useful in order to estimate the sound pressure level near the walls. If measurements are

made in the plane of the facade, subtracting 6 dB from the measured value to

approximate the free-field sound level.

4 Measurements may be performed in the plane of a facade or roof of a structure utilizing a

microphone whose protection grid or diaphragm is flush with the surface. Alternative

techniques using pressure zone microphones placed against the relevant surface may be

used.

Accordingly, to obtain free field measurement results, a subtraction of 2.5dB from the measured level

(which is performed 1m from the facade) is not required for the background LA90 noise level. Despite

this, verification testing was undertaken on 26 May 2021 to verify that the measurements obtained

previously from the fence line are consistent to short term testing taken in free field (see Table 7).

3.3.2 Long-term noise measurement results

Long-term noise monitoring was carried out from Monday, 2 September 2019 to Tuesday, 10

September 2019 and from Wednesday, 26 May 2021 to Monday, 7 June 2021. The long-term noise

monitoring methodology is detailed in APPENDIX B along with photos showing the monitoring

locations, and noise level-vs-time graphs of the data are included in APPENDIX D.


NASSCON PTY LTD


DA ACOUSTIC REPORT

As outlined in AS1055 (see Section 3.3.1) and supported by the site-specific short-term noise

measurements (see Section 3.2.1) no adjustment to the LA90 measured noise levels at Monitoring

Location L1 is required.

Table 9 presents the overall single Rating Background Levels (RBL) and representative ambient Leq noise

The shoulder period has been established for 05:00-07:00. The shoulder period rating background level is taken to be the

lowest 10th percentile of LAF90,15min dB measurements for the equivalent of one week's worth of valid data taken over the

shoulder period (that is, all days included in a single data set of shoulder period).

As required by the NPfI, the external ambient noise levels presented are free-field noise levels, ie. no facade reflection.

Comparison between monitoring L1 (2019) and L3 (2021) shows similar measured noise levels. The L3

RBL is slightly higher during the evening and night-time (within 2dB) and slightly lower during the

morning shoulder and daytime (within 1dB).

4 Project noise goals

4.1 NSW Noise Policy for Industry

Noise impact is assessed in accordance with the NSW NPfI. The assessment procedure has two

components:

• Controlling intrusive noise impacts in the short-term for residences; and

• Maintaining noise level amenity for residences and other land uses.

In accordance with the NPfI, noise impact should be assessed against the project noise trigger level

which is the lower value of the project intrusiveness noise levels and project amenity noise levels.

4.1.1 Project intrusive noise levels

According to the NPfI, the intrusiveness of a noise source may generally be considered acceptable if the

equivalent continuous (energy-average) A-weighted level of noise from the source (represented by the

LAeq,15min descriptor) does not exceed the background noise level measured in the absence of the source

by more than 5dB(A). The project intrusiveness noise level, which is only applicable to residential

receivers, is determined as follows:

LAeq,15minute Intrusiveness noise level = RBL plus 5dB(A)

Based on the background noise monitoring results and the proposed operating hours of the facility, the

intrusiveness noise levels for residential receivers are reproduced in Table 10 below.

The intrusive noise levels for R1 and R2 are based on the lowest RBL obtained at either monitoring

location L1 and L3.

1. Community expectation is that the evening period intrusive noise levels are not higher than daytime intrusive noise

levels

4.1.2 Amenity noise levels

The project amenity noise levels for different time periods of day are determined in accordance with

Section 2.4 of the NPfI. The NPfI recommends amenity noise levels (LAq,period) for various receivers

including residential, commercial, industrial receivers and sensitive receivers such as schools, hotels,

hospitals, churches and parks. These “recommended amenity noise levels” represent the objective for

total industrial noise experienced at receiver location. However, when assessing a single industrial

development and its impact on an area, “project amenity noise levels” apply.

The recommended amenity noise levels applicable for the subject area are reproduced in Table 11

below.

2. On Sundays and Public Holidays, Daytime 8.00 am - 6.00 pm; Evening 6.00 pm - 10.00 pm

3. The LAeq index corresponds to the level of noise equivalent to the energy average of noise levels occurring over a

measurement period.

4. The recommended amenity noise levels refer only to noise from industrial sources. However, they refer to noise from

all such sources at the receiver location, and not only noise due to a specific project under consideration. The levels

represent outdoor levels except where otherwise stated.

In accordance with Section 2.4 of the NPfI, when determining the project amenity noise level, a

subtraction of 5dB(A) from the recommended amenity level is not required as no other industries are

present in the area,

Given that the intrusiveness noise level is based on a 15-minute assessment period and the project

amenity noise level is based on day, evening and night assessment periods, the NPfI provides the

following guidance on adjusting the LAeq,period level to a representative LAeq,15minute level in order to

standardise the time periods.

LAeq,15minute = LAeq,period + 3dB(A)

4.1.3 Project noise trigger levels

In accordance with the NPfI the project noise trigger levels, which are the lower (ie. more stringent)

value of the project intrusiveness noise level and project amenity noise level, have been determined as

shown in Table 13 below.

3. Day: 7:00 to 18:00 Monday to Saturday and 8:00 to 18:00 Sundays & Public Holidays

4. Evening: 18:00 to 22:00 Monday to Sunday & Public Holidays

4.1.4 Sleep disturbance noise levels

The potential for sleep disturbance from maximum noise level events from premises during the night-

time period needs to be considered. In accordance with NPfI, a detailed maximum noise level event

assessment should be undertaken where the subject development night-time noise levels at a

residential location exceed:

• LAeq,15min 40dB(A) or the prevailing RBL plus 5dB, whichever is the greater, and/or

• LAFmax 52dB(A) or the prevailing RBL plus 15dB, whichever is the greater.


NASSCON PTY LTD


DA ACOUSTIC REPORT

Where there are noise events found to exceed the initial screening level, further analysis is undertaken

to identify:

• The likely number of events that might occur during the night assessment period,

• The extent to which the maximum noise level exceeds the rating background noise level.

The sleep disturbance noise levels for the project are presented in Table 14.

4.2 NSW Road Noise Policy

4.2.1 Noise assessment criteria - residential land uses

Table 3 of the NPfI sets out the assessment criteria for residences to be applied on particular types of

project, road category and land use. These criteria are for assessment against facade corrected noise

levels when measured in front of a building facade. In accordance with Table 3, Botany Street, Xenia

Avenue and Ethel Lane would be classified as Local Roads. Table 15 shows the applicable criteria for

these roads.

Note: Land use developers must meet internal noise goals in the Infrastructure SEPP (Department of Planning NSW 2007) for

sensitive developments near busy roads (see Appendix C10).

Where existing traffic noise levels are above the noise assessment criteria, the primary objective is to

reduce these through feasible and reasonable mitigative measures to meet the assessment criteria. A

secondary objective is to protect against excessive decreases in amenity as the result of a project by

applying the relative increase criteria.

In assessing feasible and reasonable mitigation measures, an increase of up to 2 dB represents a minor

impact that is considered barely perceptible to the average person.

For existing residences and other sensitive land uses affected by additional traffic on existing roads

generated by land use developments, any increase in the total traffic noise level (where the assessment

criteria cannot be achieved) should be limited to 2 dB above that of the corresponding ‘no build option’.

5 Noise emission assessment

5.1 Noise sources

Noise emission from the subject site, as is assessable against the established noise goals, includes:

• Noise breakout from internal areas (for maximum 120 patron event):

Male mosque (maximum 80 patrons) - located on ground floor (with first floor void

above), along the southern facade.

Female mosque (maximum 40 patrons) - located on the first floor, along the southern

facade.

• Noise from patrons external to the building:

Potential patron speech when people transitioning between carpark and building

entries located on the northern facade.

Potential patron speech when people transitioning between footpath and building entry

located on the western facade.

• Vehicle movements and car parking

16 carpark spaces located along the northern boundary of the site, with access located

along Botany Street.

4 carpark spaces located on the south east corner of the site (for staff use), with access

located along Xenia Avenue.

2 carpark spaces located on the south west corner of the site, with access located along

Botany Street.

• Mechanical services plant and equipment

5.1.1 Noise breakout from internal areas

The noise source levels used for the predictions, presented in Table 16, are based on the noise source

and the mosque room(s) dimensions and reverberation characteristics. The noise levels presented are

considered conservative and are higher than what is expected from the various areas of the premises.

Below outlines why the noise levels are conservative, which was confirmed by the Sheikh at the Council

meeting on 2 July 2020.

• A Mu’azzin will call the prayer (internally) for a maximum of 1 – 2 minutes at the start of each

prayer session. The Sheikh leads the prayer and will speak for a maximum of 5 minutes for

morning prayers and for afternoon and evening prayers, approximately 1 minute each prayer

session.


NASSCON PTY LTD


DA ACOUSTIC REPORT

Renzo Tonin and Associate’s assessment is based on the Sheikh or Mu'azzin speaking

for a combined 15-minute duration.

• Patrons do not speak at all during a prayer but only say ‘armin’ which equates to about 30

seconds in total for each prayer. During a prayer there is no chanting.

Renzo Tonin and Associate’s assessment is based on 50% of the patrons speaking

continuously for the whole 15-minute assessment period. This would also address any

situations where patrons are speaking among themselves prior to the prayer

commencing but this is not accepted behaviour/practice.

This assessment is based on a worst case with patrons and Sheikh speaking

simultaneously.

Breakout noise from all other internal areas, including the use of community spaces which are always

ancillary to the mosque and not to be used simultaneously as prayer services, are considered to be

negligible in impact and have not been addressed further in this report. Furthermore, the Plan of

Management (PoM) states the following; outside of (all) prayer times, community activities are

permitted to take place… between 10am and 2pm. The community rooms do not operate during prayer

services… all other activities cease, users of the community rooms (and non-praying areas) are asked to

vacate approximately 30 minutes prior to prayer services commencing. This equates to a window for

community uses as follows:

• Fridays – 1.5 hours per day

• All other days - 3 hours per day

These rooms are predominantly used for quiet meetings or gatherings of the community senior and

youth members

The community rooms and functions are informal with sporadic usage and varying attendee numbers

ranging from 10 – 40. The modelling of this is unnecessary due to the proposed times that community

uses are allowed to take place, and that all other sensitive and outlier events (100/120 persons and 20

people in the night shoulder) have been modelled extensively. We deem this to be a non-issue,

especially as the community uses are an ancillary use to the primary purpose of the POPW.

The development will be mechanically ventilated. For the purpose of assessment, all windows and doors

will be closed at all times, except for ingress/egress of patrons and staff.

2. Assumes Sheikh or Mu'azzin speaking for a combined 15 minutes

5.1.2 Noise from patrons external to the building

The path that patrons will take to enter and exit the building will be from the northern carpark to the

entries located on the northern facade and from Botany Street footpath to the Botany Street building

entry located on the western facade. The location of the building entries are shown in Figure 4 and

Figure 5.

As a part of the Plan of Management (PoM) and other instructive measures, it will be managed so that

visitors are not to talk, particularly for the dawn prayer sessions, or be greeted at the door until they are

well inside the building. Nevertheless, predictions have been made for the potential of patron speech

occurring external to the building.

The noise source levels used for the predictions, are presented in Table 19 and all assumptions have

been corrected for a 15-minute assessment period. Normal voice levels have been used for the

assessment as raised voice is typically used for restaurants, pubs and clubs where patrons are actively

engaging in conversation and/or where alcohol is involved. In this situation, any conversation that will

occur external to the building will be passive in nature. Staff will be in place to control the noise from

external patrons.

During morning shoulder operations (20 patron capacity), it has been assumed that:

• The carpark will be filled or emptied in less than 10 minutes with 20 patrons entering or

exiting from the northern entry doors to get access to their cars.

It has been assumed that 50% of people will talk at once for a duration of 3 minutes

before getting into their cars.

before reaching the footpath.

The latest prayer finishes at 9:45pm which allows 10 minutes for all the patrons to leave the site. We

have assessed and estimated that the egress of 120 patrons in 10 minutes from the premises is

achievable and relatively conservative.

The vacation of 120 (or less people) to clear a large building with multiple exits efficiently and effectively

is not a complicated or difficulty process. In the irregular 120 persons event, that equates to 12 people

per minute, over 10 minutes. That is 1 person every 5 seconds. The mosque has 2 exit points, one of

which is a double-width door with auto sliding function. During these events, the POPW will have 2 staff

for 100 persons events and up to 3 staff for 120 person event. Staff will be trained and familiar with the

PoM and will be dedicated to assisting and encouraging worshippers to vacate through any of the two

exits, ensuring the POPW is being vacated of worshippers and that people exit the premises during

these prayer sessions (that are irregular occurrences given the influence of the Lunar calendar (see

Section 5.4 of PoM)).

Furthermore, the Ramadan operates on a Lunar Calendar. Therefore, the next time late Ramadan prayer

sessions will occur will be in the year 2029, where there will be 11 prayer sessions that would end at

9:45pm, in 2030 – 21 days, in 2031 – 29-30 days, in 2032 – 22 days and in 2033 – 15 days. Late prayer

sessions would not occur for another 28 years after 2033.

In summary, ten minutes allow plenty of time for patrons to leave site for the 9:55pm premises closing

time, leaving a 5-minute buffer period before the night-time period commences at 10:00pm. As a result,

assessment against the night-time period is not required.

Given the small numbers involved (at southwestern 2 car spaces), any patron speech associated with the

south west carpark is considered insignificant and has not been addressed further.

5.1.3 Vehicle movements and car parking

In accordance with GTA traffic assessment, 97% of patrons will arrive via car and at a rate of 1.5 persons

per car. The development proposes a Mu’azzin total of 22 car parking spaces, with 16 located along the

northern boundary, 4 located on the south east corner of the site and 2 located on the south west

corner of the site. The location of the carparks is shown in Figure 4. The car park entrances for the 16

space and 2 space carparks are along Botany Street and for the 4 space carpark along Xenia Avenue.

Noise generated by car parking activities includes vehicle doors closing, vehicle engines starting,

vehicles accelerating and vehicles moving. Input sound power level data within Table 18, was calculated

from site measurements of customers at the upper level carpark of Woolworths, Caringbah of 26 door

and boot closures, 13 engine starts, 11 motor vehicles moving at 10kph.

During the morning shoulder, it has been advised that a maximum of 20 patrons are expected for the

dawn prayer for a 20 minute duration. Based on the patron to vehicle ratio within the GTA traffic report

of 1.5 passengers per car and allowing for 1 staff member, a maximum of 14 cars are expected to either

arrive or depart per 15-minute period. During the morning shoulder (dawn session), only the northern

carpark will be utilised. The earliest time the dawn prayer service will commence is 5:30am.

During the daytime and evening, it has been conservatively assumed that the 16 space and 2 space

carparks will be filled or emptied within a 15-minute period as these carparks will be used by patrons.

The 4 space carpark will be used by staff and it is assumed that 50% of the carpark will be filled or

emptied within a 15-minute period. This is a total of 20 cars to arrive or depart per 15-minute period.

During the night-time (10:00pm to 5:00am), the last prayer of the day finishes at 9:45pm and doors

close at 9:55pm. The carpark will be empty before 10:00pm. Therefore, assessment against the night-

time period is not required.

The sound power levels generated by car park activities on site are presented in Table 19. The sound

power levels have been calculated with Renzo Tonin & Associates software and its derived sound power

level database, shown in Table 18. The LAeq noise level was determined for the relevant time period

based on the number of vehicle activities expected to occur during that period,

5.2 Fencing and screens

Numerous fence heights and locations were investigated and analysed before adopting the below

arrangement. A balance was sought between designing a solution that would complement the natural

contours of the existing ground level, minimise visual impact and maximise acoustic mitigation. The

analysis for sleep disturbance is driven by the sleep disturbance noise assessment rather than the

LAeq(15minute) assessment. The analysis is further detailed within Section 5.3.4 - Maximum noise level

assessment, which includes the base scenario for a uniform 1.8m high fence around the whole property

and the benefits of strategically increasing the height of the fence along a section of the eastern side of

the northern carpark.

The following property fencing for the site was adopted and is shown in Figure 4. All fencing is located

on the property boundary and heights are above existing ground level as surveyed.

• Property fencing of 1.8 metres high along the eastern boundary of the site.


NASSCON PTY LTD


DA ACOUSTIC REPORT

• A property fence of 2.2 metres high with a 1.5 metre horizontal cantilever along the southern

side of the south east carpark and south west carpark. Property fencing of 1.8 metres high

along the remaining portion of the southern boundary of the site.

• Property fencing of 1.8 metres high along the western, northern, and southern sides of the

northern carpark.

• A property fence of 1.8 to 2.4 metres high along a portion of the eastern side of the northern

carpark. The fence is 21 metres long, with a height of 1.8 metres at the north east corner of

the site, a height of 2.4 metres at the mid-point and a height of 2.4 metres at the southern

end, see Figure 3.

The following acoustic screens to mitigate mechanical noise were adopted and are shown in Figure 6.

The screen heights are above roof level.

• A 1 metre high screen on the eastern and southern side of condenser units 1 and 2.

• A 1 metre high screen on the southern side of condenser units 5 and 6.

5.3 Noise Predictions and methodology

5.3.1 Methodology

The noise predictions were based upon the architectural drawing set out within the reference material,

see Section 2.5, and carried out in accordance with ISO9613 as implemented by CadnaA computer

modelling program. The software takes into account sound radiation patterns, acoustic shielding and

potential reflections from intervening building elements, and noise attenuation due to distance. In

addition, for noise transmission through building envelopes, the noise predictions were carried out

using computational software developed by Renzo Tonin & Associates, which takes into account noise

levels and transmission losses from intervening building elements.

The following assumptions regarding the acoustic performance of the building envelope design have

been made for the acoustic assessment.

Table 22 presents the predicted noise emission levels at the identified assessment locations against the

morning shoulder noise goals. Table 23 presents the predicted noise emission levels at the identified

assessment locations against the daytime and evening noise goals.

For the morning shoulder period, noise levels are predicted to be at least 6 dB(A) below the criteria. For

the daytime and evening period, noise levels are predicted to be at least 2 dB(A) below the criteria.

Provided the recommendations in Section 7 are implemented, noise levels are predicted to comply with

the established noise goals at all of the identified receivers for all time periods.

In addition to R3 and R4, there are some other additional residential receivers located across Botany

Street where exceedances of the sleep assessment level are predicted. Physical mitigation measures (i.e.

property fence or gate) have been deemed to have limited effect.

Further analysis of the number of project related LAmax events and the existing prevalence of LAmax events,

is provided in the below section.

5.3.4 Maximum noise level assessment

In accordance with Section 4.1.4, a detailed maximum noise level event assessment has been

undertaken and provided in the below sections.

5.3.4.1 RNP Sleep disturbance guidance

With regard to sleep disturbance, Section 2.5 of the NPfI refers to the RNP for guidance. From the

research on sleep disturbance to date the RNP concludes that:

1. LAmax (the maximum A-weighted noise level) internal noise levels below 50–55 dB(A) are

unlikely to awaken people from sleep (corresponding to approximately 60-65 dB(A) external);

and,

2. one or two noise events per night, with maximum internal noise levels of 65-70 dB(A)

(corresponding to approximately 75-80 dB(A) external), are not likely to affect health and

wellbeing significantly.


NASSCON PTY LTD


DA ACOUSTIC REPORT

5.3.4.2 Predictions

The predicted project related LAMax noise level range and number of events for surrounding receivers is

provided in Table 27, based on the fencing described in Section 5.1.4. For comparison, the same analysis

has been undertaken for fencing of 1.8 metres high and is provided in Table 26. The comparison

highlights the acoustic benefits of strategically increasing the barrier height along the eastern side of

the northern carpark.

Events are based on 21 car door slams between 5am and 6am and 21 car door slams and 14 engine

starts between 6am and 7am. Project related events have been predicted at the window of the nearest

residential receivers (4.0m to 4.5m above ground level for upper floors).

Also provided is the existing (non-project related) LAMax events, based on noise measurement location

L2. The extent and number of existing events are considered conservative (and likely to be higher),

particularly for Botany Street receivers, as measurement location L2 was located at the rear of the

property and 2m above the ground with significant shielding from Botany Street. Whereas the most

sensitive assessment points (i.e. windows) of the surrounding residences are elevated (4m and greater

above the ground) with more exposure to Botany Street.

5.3.4.3 Discussion

As shown within Table 27, the predicted maximum LAMax noise level from the project is 56dB(A) external,

which is well below the guidance provided in the RNP, see Section 5.3.4.1. Furthermore, the results

within Table 27 show that there is a significant amount of existing non-project related LAMax activity (225

events between 5am and 7am) that are occurring above the sleep disturbance assessment level of

52dB(A). The percentage increase due to the proposed project is relatively low, at less than 12%. In

addition, the number of project related events occurring at any one property above 55dB(A) is

comparatively low with 1 event between 5am and 6am and 2 events between 6am and 7am,

representing less than a 3% increase and again considered acceptable from an impact point of view.

Determination of the shoulder period RBLs (i.e. background noise levels) within Table 9, show that the

morning shoulder period background noise levels (attributed to traffic noise) are substantially higher

than the night-time and are equal to or just below the daytime. This trend is also visually shown within

the APPENDIX D logger graphs. In accordance with Section 4.1.4, predictions show that the maximum

LAMax noise level is predicted to be up to 18dB higher than the morning shoulder period RBL and 8dB

higher than the LAeq ambient noise level.

Comparisons of the results for 1 Ethel Street in Table 26 and Table 27, shows a clear acoustic benefit to

strategically increasing the fence height to 2.4m along a portion of the eastern side of the carpark. The

improvements of this modest increase in fencing height include a 5dB(A) reduction in the predicted

maximum LAMax noise level and approximately a 56% reduction in the number of project related

exceedance events, that is, from 48 to 21. This is considered a positive outcome. Note, modelling was

also undertaken to sensitivity test the effect of increasing the barrier height to approximately 3m high in

order to further meet the guidance provided in the RNP at 1 Ethel Street. Whilst the results improved

considerably, comprising an 8dB(A) reduction from the base case (i.e. Table 26), it resulted in a barrier

height that was deemed to have reduced visual amenity and was therefore omitted.

As previously noted, for receivers located on the opposite side of Botany Street, physical mitigation has

been deemed to have limited effect. Whilst solutions such as gate installation and the like are possible,

these receivers are already exposed to a significant amount of traffic noise, which is travelling at speed

and in much closer proximity than the carpark. As such these receivers are not considered as sensitive

and given the existing ambient environment, as demonstrated with the acoustic logging undertaken for

the area that shows RBL being relatively high for the morning shoulder period, the project related LAMax

activity is considered reasonable.

6 Road traffic noise assessment

Additional noise from traffic generated by a development on the local road network is assessed against

the RNP. The assessment involves consideration of the existing traffic noise levels and the potential

change in noise as a result of the development.

Traffic generated by the development would access and depart the site via Botany Street which has

been classified as a local road with a LAeq,(1 hour) criteria of:

• Day (7:00am-10:00pm) - 55dBA

• Night-time (10:00pm-7:00am) - 50dBA

In addition to the traffic generation along Botany Street, some traffic associated with the south east

carpark will utilise Xenia Avenue. Given the carpark is existing, has a low capacity (4 spaces) and will be

used by staff with infrequent arrival and departure times (i.e. at the start and end of the day), the

additional traffic generated by the development is considered to be acoustically insignificant.

6.1 Prediction methodology

The assessment was carried out in accordance with the RNP, in particular Section B3 Noise monitoring

procedures. Given the low traffic volumes associated with the project, the 'Calculation of Road Traffic

Noise (1988)' known as the CoRTN (1988) method, is not appropriate. Noise modelling for the project

was carried out using CadnaA software using the below methodology:

1. Measured traffic noise levels undertaken at monitoring location L4 was used to calibrate

existing LAeq,(1hour) traffic noise levels predicted at the nearest residential receivers shown in

Figure 7, for the morning shoulder period and daytime.

2. Based on the site-specific calculated sound power levels for car pass-bys and cars

entering/leaving site within Table 8, project related LAeq,(1hour) traffic noise levels were

predicted at the nearest residential receivers for the morning shoulder period and daytime.

See below traffic volume details:

• Shoulder period (20min prayer duration) - based on worst case dawn prayer which has

maximum patronage of 20 people (14 cars with 1.5 passengers per car, equivalent to 28

car movements per hour).

• Daytime (60min prayer duration) - based on worst case day prayer which has maximum

patronage of 120 people (80 cars with 1.5 passengers per car, equivalent to 80 car

movements per hour). Includes 16 cars (16 movements) utilising the northern carpark

and 2 cars (2 movements) utilising the south-west carpark.

3. Calculation of the Total LAeq,(1hour) traffic noise levels (Existing plus Project).

4. Determine predicted increase in noise level between Existing and Total traffic noise levels.

utilising the south-west carpark.

In accordance with the RNP, in assessing feasible and reasonable mitigation measures, an increase of up

to 2 dB represents a minor impact that is considered barely perceptible to the average person.

For existing residences and other sensitive land uses affected by additional traffic on existing roads

generated by land use developments, any increase in the total traffic noise level (where the assessment

criteria cannot be achieved) should be limited to 2 dB above that of the corresponding ‘no build option’.

As the predicted noise level increases presented in Table 28 and Table 29 are not more than 2dB(A), the

road traffic noise generated by vehicles associated with the proposed development is considered to

comply with RNP criteria.

7 Recommendations

The following recommendations provide in-principle solutions to address Project acoustic requirements.

This information is presented for the purpose of consent authority approvals process and cost planning

and shall not be used for construction unless otherwise approved in writing by the acoustic consultant.

Assistance of an acoustic consultant must be sought during the detailed design phase of the project in

order to confirm all details and specification.

Before undertaking any variations to the proposed design as part of this development application,

advice should be sought from an acoustic consultant to ensure that adequate provisions are made for

any variations which may occur as a result of changes to the project.

The advice provided here is in respect of acoustics only. Supplementary professional advice may need

to be sought in respect of fire ratings, structural design, buildability, fit for purpose and the like.

The following is provided in addition to the operational scenarios presented for the assessment.

7.1 Plan of Management

It is recommended that the necessary controls be further refined and determined during post-operation

compliance testing and incorporated into the approved Plan of Management.

7.2 Acoustic performance of building envelope

• This assessment has assumed closed windows/doors to have a moderate acoustic

performance of RW 26 (indicatively 6mm float glass) and RW 21 for male mosque skylight.

Higher acoustic performance can be readily achieved through the provision of improved

glazing and/or sealing of areas of noise emission if necessary, however, this assessment has

not deemed additional improvements being needed.

Windows and doors of the development to be closed at all times. Mechanical

ventilation to be provided

7.3 Carpark usage

• During the morning shoulder period (5:30am to 7:00am) only the northern carpark will be

utilised, and the maximum number of cars to be restricted to 14. As previously stated, the

development is not operational after 10:00pm.

7.4 External patrons

• All staff are required to study and uphold the approved PoM as well as carry out any actions

and implement any requirements arising from the use of the development.


NASSCON PTY LTD


DA ACOUSTIC REPORT

• As a part of the PoM and other instructive measures, it will be managed so that visitors are

not to talk, particularly for the dawn prayer sessions, or be greeted at the door until they are

well inside the building.

• The staff members will provide the following services in accordance with the PoM, including

managing the centre, managing the attendees (ensuring all attendees participate in

scheduled activities in a safe and orderly manner), community liaison, traffic marshalling and

entry management.

• At least one staff member is on site during all operating times of the development. Two

administration staff are required to administer support for up to 100 worshippers (Friday

communal). During peak periods of 100 or 120 worshippers (such as Friday communal, Easter

Friday and other Friday prayers that fall on a public holiday, or first two days and last days of

Ramadan), additional staff (minimum of 3) are required to assist with events and

management of the premises. This includes traffic marshals to manage parking during special

prayer sessions.

7.5 Fencing and screens

7.5.1 Fencing

The following fencing is required and shown in Figure 4. All fencing is located on the property boundary

and heights are above existing ground level as surveyed.

• Property fencing of 1.8 metres high along the eastern boundary of the site.

• A property fence of 2.2 metres high with a 1.5 metre horizontal cantilever along the southern

side of the south east carpark and south west carpark. Property fencing of 1.8 metres high

along the remaining portion of the southern boundary of the site.

• Property fencing of 1.8 metres high along the western, northern, and southern sides of the

northern carpark.

• A property fence of 1.8 to 2.4 metres high along a portion of the eastern side of the northern

carpark. The fence is 21 metres long, with a height of 1.8 metres at the north east corner of

the site, a height of 2.4 metres at the mid-point and a height of 2.4 metres at the southern

end.

7.5.2 Screens

The following acoustic screens to mitigate mechanical noise are required and are shown in Figure 6. The

screen heights are above roof level.

• A 1 metre high screen on the eastern and southern side of condenser units 1 and 2.

• A 1 metre high screen on the southern side of condenser units 5 and 6.


NASSCON PTY LTD


DA ACOUSTIC REPORT

7.5.3 Fence and screen construction

In addition to the above, all fences and screens should give regard to the following to maintain acoustic

integrity and for the fences to perform as noise screens:

• An acoustically rated fence can be constructed of common building materials but needs to

be from a durable material with sufficient mass (min. 10kg/m2) to prevent direct noise

transmission eg. masonry, fibrous-cement, lapped and capped timber fence, polycarbonate,

or any combination of such materials, provided they meet material requirements and

withstand weather elements.

• Any penetrations through the fabric of the fence should be sealed airtight with a suitable

material of suitable density.

• All joints and gaps between fence panels / planks should be sealed airtight with a suitable

material of suitable density.

• Any gaps between the fence and the ground / retaining walls should be filled with a suitable

material of suitable density to ensure that the fence provides appropriate noise attenuation.

7.6 Mechanical plant and equipment

A quantitative assessment of mechanical plant associated with the development has been assessed

within Section 5.

7.7 Noise monitoring program

The following approach will be adopted with regard to noise monitoring during the first 12 months of

operation (i.e. during the requested 12-month trial period).

Within first month and last month of the 12-month trial period, noise monitoring will be undertaken by

a qualified acoustic engineer to verify that the mosque is complying with the noise criteria set within

Table 13 and is consistent or below the LAmax predictions within Table 27. Given the amount of

extraneous noise sources in the vicinity of the site (i.e. road traffic), so that site noise emission can be

more readily quantified, short-term attended noise monitoring and long-term compliance monitoring

with audio recording is recommended. Details of the procedures for noise monitoring are presented in

APPENDIX C, which outlines short-term and long-term methodology.

The noise monitoring program is outlined in Table 30 and the noise monitoring locations are identified

in Table 31.

8 Acoustic risk assessment

Risk management is an integral part of good management practice. Australian/New Zealand Standard

AS/NZS 4360:2004 “Risk management” has become part of our company’s culture and as a

consequence it permeates all aspects of the company’s work and is actively promoted to our clients.

The risk management process can be applied to any situation where an undesired or unexpected

outcome could be significant or where opportunities are identified. Our clients need to know about

possible outcomes and the steps that can be taken to control any adverse impact.

There is an opportunity in the design process for the client to actively participate in risk management by

providing input into risk reduction strategy. For example, the client may need to know that some

aspects of risk reduction could involve passing those risks on to other entities in a better position to

treat those risks. Some aspects of risk reduction may involve additional cost or time consequences. On

the other hand, there may also be opportunities to avoid or avert risk at no cost to the client by

rescheduling processes so that key information becomes available at a critical time.

When the client is properly informed, this supports better decision making by contributing a greater

insight into risks and their impacts. It is recommended that the client seek to understand the potential

risk during the detailed design phase of the development.

9 Conclusion

Renzo Tonin & Associates has completed an assessment of operational noise to support the

development application for the proposed place of worship (Mosque) and community centre, located at

88-90 & 92 Botany Street, Carlton.

The 2019 noise assessment [Ref: TL074-01F02 DA Acoustic Assessment (r1), dated 20 December 2019]

was undertaken against and with respect to NSW Noise Policy for Industry (NPfI) and the NSW Road

Noise Policy (RNP). As a continually evolving process over 2020 and 2021 additional requests for

information as well as independent peer reviewed material has driven update to the original assessment

by Renzo Tonin. This continued assessment has confirmed earlier results and assumptions as well as

further strengthened the proposed development. The original assessment was based upon industry-

accepted and recognised practices and the new assessments seek to exceed these requirements

through additional analysis and field data. In addition, 2021 field analysis confirmed that assumptions

made in 2019 were consistent and equally able to be relied upon for noise assessment.

The main sources of acoustic generation relates to noise emissions from internal areas, external

emission from patrons when entering and leaving the site, on-site vehicle movements including

carparks, mechanical plant and traffic noise on the public road. The proposed works have been assessed

against all relevant noise criteria at the nearest sensitive receivers.

Particular concern was raised by the peer reviewer in relation to 20-person dawn prayer services and late

evening prayer sessions in summer seasons.

Noise from the on-site car park and the vehicles using the carpark for the dawn session has been

modelled and assessed in detail. Noise and LAMax events assessed for the existing situation was found to

be relatively high, suggesting that the location already experiences relatively noisy morning periods in

the current situation without the mosque. Through the modelling of various scenarios (with varied

barrier heights), noise from the operation of the proposed development has been predicted to comply

at all surrounding receivers, except for relatively minor LAMax events associated with the car park during

the morning shoulder period, which are well below the guidance provided in the RNP.

Additional scenarios that were modelled included the worst case for the morning shoulder (20 person

prayer event) and worst case for the daytime and evening (120 person prayer event) which covers all 35

sessions through a week. With the exception of relatively minor sleep disturbance events during the 20-

person dawn session which are detailed in Section 5.3.4, all other prayer sessions and modelled

scenarios comply with the relevant guidelines, provisions and criteria. These results and scenarios are

determined to be acceptable and supportable in our professional view. Noise disturbances resulting

from the proposed development in the proposed location in its current environmental context would be

minimal and acceptable. The results of the assessments and field work undertaken in 2019, 2020 and

2021 conclude that noise from the proposed development is predicted to comply. It has been

established that the proposed development able to be supported with adoption of recommendations

outlined in Section 7.


NASSCON PTY LTD


DA ACOUSTIC REPORT

The extensive noise monitoring program as part of Renzo Tonin & Associate’s Recommendations are to

be adopted for the development and would further ensure that the mosque operates at its expected

performance and ensures that should non-compliances occur that they are identified and addressed.

APPENDIX A Glossary of terminology

The following is a brief description of the technical terms used to describe noise to assist in

understanding the technical issues presented.

Absorption Coefficient

α

The absorption coefficient of a material, usually measured for each octave or third-octave band

and ranging between zero and one. For example, a value of 0.85 for an octave band means that

85% of the sound energy within that octave band is absorbed on coming into contact with the

material. Conversely, a low value below about 0.1 means the material is acoustically reflective.

Adverse weather Weather effects that enhance noise (particularly wind and temperature inversions) occurring at a

site for a significant period of time. In the NSW INP this occurs when wind occurs for more than

30% of the time in any assessment period in any season and/or temperature inversions occurring

more than 30% of nights in winter.

Air-borne noise Noise which is fundamentally transmitted by way of the air and can be attenuated by the use of

barriers and walls placed physically between the noise source and receiver.

Ambient noise The all-encompassing noise associated within a given environment at a given time, usually

composed of sound from all sources near and far.

Amenity A desirable or useful feature or facility of a building or place.

AS Australian Standard

Assessment period

The time period in which an assessment is made. e.g. Day 7am-10pm & Night 10pm-7am.

Assessment Point

A location at which a noise or vibration measurement is taken or estimated.

Attenuation The reduction in the level of sound or vibration.

Audible Range The limits of frequency which are audible or heard as sound. The normal hearing in young adults

detects ranges from 20 Hz to 20 kHz, although some people can detect sound with frequencies

outside these limits.

A-weighting A filter applied to the sound recording made by a microphone to approximate the response of the

human ear.

Background noise

Background noise is the term used to describe the underlying level of noise present in the ambient

noise, measured in the absence of the noise under investigation. It is described as the average of

the minimum noise levels measured on a sound level meter and is measured statistically as the A-

weighted noise level exceeded for ninety percent of a sample period. This is represented as the

LA90 noise level if measured as an overall level or an L90 noise level when measured in octave or

third-octave bands.

Barrier (Noise) A natural or constructed physical barrier which impedes the propagation of sound and includes

fences, walls, earth mounds or berms and buildings.

Berm Earth or overburden mound.

Buffer An area of land between a source and a noise-sensitive receiver and may be an open space or a

noise-tolerant land use.

Bund A bund is an embankment or wall of brick, stone, concrete or other impervious material, which

may form part or all of the perimeter of a compound.

Decibel [dB] The units of sound measurement. The following are examples of the decibel readings of every day

sounds:

0dB The faintest sound we can hear, defined as 20 micro Pascal

30dB A quiet library or in a quiet location in the country

45dB Typical office space. Ambience in the city at night

60dB CBD mall at lunch time

70dB The sound of a car passing on the street

80dB Loud music played at home

90dB The sound of a truck passing on the street

100dB The sound of a rock band

110dB Operating a chainsaw or jackhammer

120dB Deafening

dB(A) A-weighted decibel. The A- weighting noise filter simulates the response of the human ear at

relatively low levels, where the ear is not as effective in hearing low frequency sounds as it is in

hearing high frequency sounds. That is, low frequency sounds of the same dB level are not heard

as loud as high frequency sounds. The sound level meter replicates the human response of the ear

by using an electronic filter which is called the “A” filter. A sound level measured with this filter is

denoted as dB(A). Practically all noise is measured using the A filter.

dB(C) C-weighted decibels. The C-weighting noise filter simulates the response of the human ear at

relatively high levels, where the human ear is nearly equally effective at hearing from mid-low

frequency (63Hz) to mid-high frequency (4kHz), but is less effective outside these frequencies. The

dB(C) level is not widely used but has some applications.

Diffraction The distortion of sound waves caused when passing tangentially around solid objects.

DIN German Standard

ECRTN Environmental Criteria for Road Traffic Noise, NSW, 1999

EPA Environment Protection Authority

Field Test A test of the sound insulation performance in-situ. See also 'Laboratory Test'

The sound insulation performance between building spaces can be measured by conducting a

field test, for example, early during the construction stage or on completion.

A field test is conducted in a non-ideal acoustic environment. It is generally not possible to

measure the performance of an individual building element accurately as the results can be

affected by numerous field conditions.

Fluctuating Noise Noise that varies continuously to an appreciable extent over the period of observation.

Free-field An environment in which there are no acoustic reflective surfaces. Free field noise measurements

are carried out outdoors at least 3.5m from any acoustic reflecting structures other than the

ground.

Frequency Frequency is synonymous to pitch. Sounds have a pitch which is peculiar to the nature of the

sound generator. For example, the sound of a tiny bell has a high pitch and the sound of a bass

drum has a low pitch. Frequency or pitch can be measured on a scale in units of Hertz or Hz.

Ground-borne noise Vibration propagated through the ground and then radiated as noise by vibrating building

elements such as wall and floor surfaces. This noise is more noticeable in rooms that are well

insulated from other airborne noise. An example would be vibration transmitted from an

underground rail line radiating as sound in a bedroom of a building located above.

Habitable Area Includes a bedroom, living room, lounge room, music room, television room, kitchen, dining room,

sewing room, study, playroom, family room, home theatre and sunroom.

Excludes a bathroom, laundry, water closet, pantry, walk-in wardrobe, corridor, hallway, lobby,

photographic darkroom, clothes drying room, and other spaces of a specialised nature occupied

neither frequently nor for extended periods.

Heavy Vehicle A truck, transporter or other vehicle with a gross weight above a specified level (for example: over

8 tonnes).

For example, a material with alpha = 0.65 and a surface area of 8.2m2 would have 0.65 x 8.2 = 5.33

Sabine.

Sabine is usually calculated for each individual octave band (or third-octave).

SEL Sound Exposure Level (SEL) is the constant sound level which, if maintained for a period of 1

second would have the same acoustic energy as the measured noise event. SEL noise

measurements are useful as they can be converted to obtain Leq sound levels over any period of

time and can be used for predicting noise at various locations.

Sound A fluctuation of air pressure which is propagated as a wave through air.

Sound absorption The ability of a material to absorb sound energy by conversion to thermal energy.

Sound Insulation Sound insulation refers to the ability of a construction or building element to limit noise

transmission through the building element. The sound insulation of a material can be described by

the Rw and the sound insulation between two rooms can be described by the DnT,w.

Sound level meter An instrument consisting of a microphone, amplifier and indicating device, having a declared

performance and designed to measure sound pressure levels.

Sound power level Ten times the logarithm to the base 10 of the ratio of the sound power of the source to the

reference sound power of 1 pico watt.

Sound pressure level The level of noise, usually expressed in decibels, as measured by a standard sound level meter with

a microphone referenced to 20 mico Pascal.

Spoil Soil or materials arising from excavation activities.

STC Sound Transmission Class

A measure of the sound insulation performance of a building element. It is measured in controlled

conditions in a laboratory.

The term has been superseded by Rw.

Structure-borne Noise Audible noise generated by vibration induced in the ground and/or a structure. Vibration can be

generated by impact or by solid contact with a vibrating machine.

Structure-borne noise cannot be attenuated by barriers or walls but requires the isolation of the

vibration source itself. This can be achieved using a resilient element placed between the

vibration source and its support such as rubber, neoprene or springs or by physical separation

(using an air gap for example).

Examples of structure-borne noise include the noise of trains in underground tunnels heard to a

listener above the ground, the sound of footsteps on the floor above a listener and the sound of a

lift car passing in a shaft. See also 'Impact Noise'.

Tonal Noise Sound containing a prominent frequency and characterised by a definite pitch.

Transmission Loss The sound level difference between one room or area and another, usually of sound transmitted

through an intervening partition or wall. Also the vibration level difference between one point and

another.

For example, if the sound level on one side of a wall is 100dB and 65dB on the other side, it is said

that the transmission loss of the wall is 35dB. If the transmission loss is normalised or

standardised, it then becomes the Rw or R'w or DnT,w.

APPENDIX B Long-term noise monitoring methodology

B.1 Noise monitoring equipment

A long-term unattended noise monitor consists of a sound level meter housed inside a weather

resistant enclosure. Noise levels are monitored continuously with statistical data stored in memory for

every 15-minute period.

Long term noise monitoring was conducted using the following instrumentation:

Description Type Octave band data Logger location(s)

RTA06 and RTA07 (NTi Audio XL2) Type 1 1/1 L1, L2, L3 and L4.

Notes: All meters comply with AS IEC 61672.1 2004 “Electroacoustics - Sound Level Meters” and designated either Type 1 or Type 2 as

per table and are suitable for field use.

The equipment was calibrated prior and subsequent to the measurement period using a Brüel & Kjær

Type 4231 calibrator. No significant drift in calibration was observed.

B.2 Meteorology during monitoring

Measurements affected by extraneous noise, wind (greater than 5m/s) or rain were excluded from the

recorded data in accordance with the NSW NPfI. Determination of extraneous meteorological

conditions was based on data provided by the Bureau of Meteorology (BOM), for a location considered

representative of the noise monitoring location(s). However, the data was adjusted to account for the

height difference between the BOM weather station, where wind speed and direction is recorded at a

height of 10m above ground level, and the microphone location, which is typically 1.5m above ground

level (and less than 3m). The correction factor applied to the data is based on Table C.1 of ISO

4354:2009 'Wind actions on structures'.

B.3 Noise vs time graphs

Noise almost always varies with time. Noise environments can be described using various descriptors to

show how a noise ranges about a level. In this report, noise values measured or referred to include the

L10, L90, and Leq levels. The statistical descriptors L10 and L90 measure the noise level exceeded for 10%

and 90% of the sample measurement time. The Leq level is the equivalent continuous noise level or the

level averaged on an equal energy basis. Measurement sample periods are usually ten to fifteen

minutes. The Noise -vs- Time graphs representing measured noise levels, as presented in this report,

illustrate these concepts for the broadband dB(A) results.

APPENDIX C Specification for noise monitoring

C.1 Scope

This document specifies methods for undertaking noise monitoring during mosque operation.

C.2 Referenced Standards and Guidelines

• Australian Standard AS IEC 61672.1 2004 ‘Electroacoustics - Sound Level Meters -

Specifications’

• Australian Standard AS 1259.2-1990 'Acoustics - Sound Level Meters'

• Australian Standard AS 1055-2018 ‘Acoustics - Description and Measurement of Environmental

Noise’

• NSW ‘Noise Policy for Industry’ (Environment Protection Authority 2017)

C.3 Testing Procedures

The following procedures are to be followed by personnel suitably qualified and experienced in

undertaking acoustic measurements.

All noise monitoring equipment used must be at least Type 2 instruments as described in AS 1259.2-

1990 and calibrated to standards that are traceable to Australian Physical Standards held by the

National Measurement Laboratory (CSIRO Division of Applied Physics). The calibration of the monitoring

equipment shall also be checked in the field before and after the noise measurement period, and in the

case of long-term noise monitoring, calibration levels shall be checked at minimum weekly intervals.

All environmental noise measurements shall be taken with the following meter settings:

• Time constant: FAST (ie 125 milliseconds)

• Frequency weightings: A-weighting

• Sample period: 15 minutes

All outdoor noise measurements shall be undertaken with a windscreen over the microphone.

Windscreens reduce wind noise at the microphones.

Measurements of noise should be disregarded when it is raining and/or the wind speed is greater than

5m/s (18km/h).

C.4 Long-term (unattended) monitoring

Noise monitoring shall be undertaken in accordance with the environmental noise measurement

requirements stipulated in the reference standards and documents listed above.


NASSCON PTY LTD


DA ACOUSTIC REPORT

Noise levels are to be recorded at a minimum rate of 10 samples per second. Every 15 minutes, the data

is to be processed statistically and stored in memory. The minimum range of noise metrics to be stored

in memory for later retrieval is the following A-weighted noise levels: Lmin, L90, Leq, L10, L1 and Lmax.

Where the noise monitors are placed within 3.5 metres of building facades, walls or cliffs, then a

reflection correction of up to -2.5dB(A) shall be applied to remove the effect of increased noise due to

sound reflections from such structures.

Meteorological conditions including wind velocity, wind direction and rainfall shall be monitored over

the entire noise monitoring period, either on site or recorded from the nearest weather station to the

project site.

C.5 Short-Term (Attended) Monitoring

Where noise complaints or requests from relevant authorities are received, attended short-term noise

monitoring may be conducted at the requested location and at any other relevant noise receiver

location with closest proximity to the facility activities.

Short-term noise monitoring could be used to supplement long-term noise monitoring undertaken at

nearby locations, and to establish whether noise levels measured by the long-term noise monitors are

determined by facility activities.

All attended short-term noise monitoring shall be recorded over 15 minute sample intervals. Noise

levels are to be recorded at a minimum rate of 10 samples per second. Every 15 minutes, the data is to

be processed statistically and stored in memory. The minimum range of noise metrics to be stored in

memory and reported is the following A-weighted noise levels: Lmin, L90, Leq, L10, L1 and Lmax.

In addition to measuring and reporting overall A-weighted noise levels, statistical L90, Leq, L10 noise levels

shall be measured and reported in third-octave band frequencies from 31.5Hz to 8kHz.

Where the noise monitors are placed within 3.5 metres of building facades, walls or cliffs, then a

reflection correction of up to -2.5dB(A) shall be applied to remove the effect of increased noise due to

sound reflections from such structures. Presence of impulsive and tonal noise, and subsequent penalty,

is to be determined in accordance with the provisions of Table 4.1 Modifying Factor Corrections of INP.

Outdoor noise monitoring is to be undertaken with the microphone at a height of 1.2 – 1.5m from the

ground, unless noise measurements are taken from a balcony or veranda, in which case the same

microphone height shall apply off the floor.

Noise measurements inside buildings should be at least 1m from the walls or other major reflecting

surfaces, 1.2 m to 1.5m above the floor, and 1.5m from windows.

Noise monitoring shall be undertaken in accordance with the environmental noise measurement

requirements stipulated in the reference standards and documents listed above.


NASSCON PTY LTD
