EFFECT OF MUSIC ON PLANT
SOUND VS NOISE
What is noise pollution?WHO Guidelines :
Noise is unwanted sound.
Sound is a vibration that propagates as a mechanical wave of pressure and displacement, through some medium
Noise pollution refers to a type of energy pollution in which distracting, irritating or damaging sounds are freely audible
Sources of noise pollution
DomesticStreet traffic Rail roadsAirplanesConstructionsConsumer products
1. Environmental noise A. Transportation Noise B. Domestic Noise2. Occupational Noise
WHO Guidelines WHO defined environmental noise as “noise emitted from all sources except for noise at the industrial workplace”.
EC Directive European Union (EU) Directive 2002/49/EC on the management of environmental noise defines environmental noise as “unwanted or harmful outdoor sound created by human activities

There are many people but less space in Hong Kong. We live in a
densely-populated city.Noise pollution is serious.

B. Domestic NoiseI ) Environmental Noise
There are many loud sounds in our surroundings, including some of the objects we often use.

EFFECT ON BEACHED WHALE
One of the best known damage caused by noise pollution is the death of certain species of beached whales, brought on by the loud sound of military sonar.

EUROPEAN ROBINS
European Robins living in urban environments are more likely to sing at night in places with high levels of noise pollution during the day, suggesting that they sing at night because it is quieter, and their message can propagate through the environment more clearly.
Control of Noise Pollution
Control at SourceControl in the Transmission PathUsing Protective Equipment
Legistation Noise Regulation Rules under the
Environment (Protection) Act of 1986. Features Industrial- 75db Commercial- 65 db Residential zones- 55 db Zones of silence No public address system after 10:00 pm and before 06:00 am.
Symptoms of occupational hearing loss Feeling of fullness in the ear.
Sounds may seem muffled.
Cannot hear high frequency sounds.
Ringing in the ears while listening to the high frequency sounds.
Loud noise for a long period of time, or sudden burst of sound can cause occupational hearing loss.
Hearing that does not return after an acute noise injury is called a permanent threshold shift.
According to an investigation done by a group of Australian scientists
in 1998:Wear headphones to listen to music for more than 6 hours a week, the sense of hearing will
decrease by 30 years.
CONCLUSION…
To protect healthy life, there is an urgent need to come up with an enforceable law on Noise Pollution in each state.

While the government has spent a lot of money on noise control,
As responsible citizens, we have the responsibility to help reduce noise pollution.
