This document discusses noise pollution from various sources and its effects. It defines noise pollution as distracting, irritating or damaging sounds and lists major sources such as transportation, construction, and consumer products. It describes how noise affects humans, animals, and the environment. Control methods include reducing noise at the source, blocking transmission paths, and using protective equipment. Legislation regulates noise limits in different areas. The document provides examples of noise damage and calls for citizens' responsibility in reducing pollution.

We can enjoy some sounds as music.
However, sound can also be
annoying noises.

5. 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

6. Sources of noise pollution
Domestic
Street traffic
Rail roads
Airplanes
Constructions
Consumer products

A. Transportation Noise
B. Domestic Noise
2. 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

 Lack of concentration
 Abortion is caused
 Pupil Dilation
 Mental Illness
 It Causes Heart Attack

23. 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.

24. 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.

25. Control of Noise Pollution
Control at Source
Control in the Transmission Path
Using Protective Equipment

27. 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.

28. 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.

29. 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.

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