(*) according to the statements of the customer.

Sample description*The sample to test is made up of a paneling laid on the floor made by the closeness of n. 3 batts in rolls, size 1000x4000 mm and thickness 60÷70 mm, in carded wool, superficial mass 3 KG/m3.The dimensional characteristics of the sample tested are the following:

- total nominal length: 4000 MM;- total nominal width: 3000 MM;- useful acoustic surface: 12.0 m2;


ACOUSTIC ABSORPTION TEST

PICTURE OF THE TESTED SAMPLE


Legal referencesThe test was performed in accordance with the requirements of norm ISO 354, 1985 “Acoustic. Measurements of sound absorption in a reverberation room” using the internal procedure of detail PP016 revision 0 of 02-29-1996 “Measure of the sound absorption coefficient in a reverberation room”.

Test equipmentFor test execution, the following equipment was used:

- power amplifier model “PWA – 202/4” of the company Masters;- loudspeaker of the company Masters;- analyzer in real time model “2123” “2123” of the company Brüel & Kajer;- microphone ø 1⁄2” model “4192” of the company Brüel & Kajer;- microphone pre-amplifiers model “2669” of the company Brüel & Kajer;- pistonophone for microphone calibration model “4220” of the company Brüel & Kajer;- completion accessories.

Test modeTest environment is made up of a reverberation room in parallelepiped shape with a rectangular base, with the following dimensional characteristics:

- plan dimensions = 8 x 6.6 m;- height “H” = 3.9 m;- base surface “S

b” = 52.8 m2;

- total surface “St” = 219.5 m2;

- volume “V” = 200 m2;

All the areas of the test environment have been treated in order to cause the maximum sound reverberation; were also present, randomly distributed and oriented, n. 11 elements slightly curved, with total land area, including both sides, about 66 m2.The test consisted in measuring times of reverberation of empty reverberation room “T

1” and of reverberation room

containing the test sample “T2” in order to determine the sound absorption coefficient “as “ of the sample; the time of

reverberation ‘T’ corresponds to the range of time, expressed in s, during which the level of sound pressure decreases of 60dB from the arrest of the source of noise. For the test is being used a generator of pink noise, a power amplifier and two dodecahedral loudspeaker omnidirectional, operating alternately to each of the six microphone positions, so to detect 12 decay of sound pressure level for each band of frequency.During the test the sample was lying on the floor of the reverberation room with the absorbing face pointing up and with the perimetric board sealed; it was also verified that the sides of sample were not parallel to the walls of the reverberation room and that were placed at a distance of not less than 1 m from the same and from every microphonic position.The measures have been made in bands of 1/

3 of eighth in the interval between 100 Hz and 5000 60hz, as requested by

norm ISO 354, 1985. The acoustic absorption coefficient “as” was calculated using the following formulas:

“as”= A/S

A = A2

- A1 = 55.3 * V/c * (1/T

2 – 1/T

1)

c = 331+0.6*t

where: as = sound absorption coefficient; A = area of sound absorption equivalent to the sample in test, expressed in m2; S = tested sample area, expressed in m2; A

2 = area of sound absorption equivalent of the reverberation room containing the tested sample, expressed in m2

A1 = area of sound absorption equivalent of the EMPTY reverberation room, expressed in m2;

V = effective useful volume of the empty reverberation room, expressed in m3. c = speed of sound propagation in the air, expressed in m/s; T

2 = time of reverberation of the reverberation room containing the tested sample, expressed in s;

T1

= time of reverberation of the empty reverberation room, expressed in s; t = temperature of the air in the reverberation room, expressed in C°.

- ISO 717 1st part, 1996 “Acoustics. Rating of sound insulation in buildings and of building elements. Part 1: Airborne sound insulation in buildings and of building elements.”

Test equipment

For test execution, the following equipment was used:

- noise generator model “1405” of the company Brüel & Kajer- power amplifier 1000 W model “ENERGY 2” of the company LEM- omnidirectional loudspeaker- third of octave equalizer model “HD-31” of the company Applied Research & Technology Inc.- microphones ø 1⁄2” model “4192” of the company Brüel & Kajer- microphone pre-amplifiers model “2669” of the company Brüel & Kajer- analyzer in real time model “2144” of the company Brüel & Kajer- analyzer in real time model “2123” of the company Brüel & Kajer- pistonophone for microphone calibration model “4220” of the company Brüel & Kajer- completion accessories

Test mode

Test environment is made up of two rooms, one of which, defined as “issuing room,” contains the noise source, while the other, defined as “receiving room,” is acoustically characterized through the equivalent acoustic absorption area.After having positioned the sample to test into the space in between the two rooms of the test area, it has been taken the sound pressure at different frequency levels, in a range between 100 Hz and 5000 Hz, both in the emitting room and in the receiving room, to verify the delay and attenuation of the sound wave for reason of the test material.

The index of evaluation “RW” of the phono insulating power “R” is equal to the value in dB of the reference curve at 500 Hz according to the proceedings of the norm ISO 717 part 1a.The phono insulating power “R”, equal to 10 times the decimal logarithm of the relationship between the incident sound power and the sound power transmitted through the sample, has been calculated using the following formula:

R= L1 – L2 + 10 z log S/A

where: R = phono insulating power, expressed in dB L1 = sound pressure medium level in the issuing room, expressed in dB L2 = sound pressure medium level in the receiving room, expressed in dB S = measuring useful surface of the sample to test, expressed in m2 A1 = acoustic absorption area equivalent to receiving room, expressed in m2, calculated by using the following formula

A = 0,163 x V T

where: V = receiving room volume, expressed in m3; T = reverberation time, expressed in s.



It has also been calculated, as proposed by norm ISO 717 part 1, 2 corrective terms in dB which considers the features of particular sound spectra in source:

- corrective term “C” to add to the index of evaluation “RW” with spectrum in source relative to pink noise Pondered A- corrective term “C” to add to the index of evaluation “RW” with spectrum in source relative to traffic noise Pondered A

Environmental condition during the test

Environment average temperature = 22° CRelative humidity = 50%

From: Andrea Bruschi Internal telephone number: 110Object: Phono insulating power measures results on your samples Pages No: 4 MESSAGE

As agreed we deliver the results of phono-insulating power tests, executed on various types of plasterboard/sheep wool panels. The following is a short description of the samples and the values:

- “R” phono-insulating power, in the field of frequencies between 100 and 5000 Hz, calculated in agreement with the ISO 140/3 of 1995- “R” index of evaluation of phono-insulating power, calculated in agreement with the ISO 717/1 of 1996;- “C” corrective term to add to “Rw” with spectrum at source relative to pink noise A weighted, calculated in agreement with the ISO 717/1 of 1996- “C” corrective term to add to “Rw” with spectrum at source relative to traffic noise A weighed, calculated in agreement with the ISO 717/1 of 1996
