Conclusion
What is Noise pollution?
Sound that is unwanted or which disrupts one’s quality of
life is called as noise. When there is lot of noise in the
environment, it is termed as noise pollution
A Human Being cannot handle noise more than 85 decibels
(dB)
What is Noise Pollution
unwanted sound that penetrates the environment is
noise pollution.
Sound becomes undesirable when it disturbs the normal
activities such as working, sleeping, and during
conversations.
It is an underrated environmental problem because of
the fact that we can’t see, smell, or taste it.
World Health Organization stated that “Noise must be
recognized as a major threat to human well-being”
Classification of Noise Pollution
There are 2 kinds of noise pollution:-
A) Community Noise/ Environmental Noise (non industrial noise pollution).
• Air craft noise
• Roadway noise pollution
• Under water noise pollution
B) Occupational Noise( industrial noise pollution)
Community Noise Community noise (also called environmental noise, residential noise
or domestic noise) is defined as noise emitted from all sources,
except at the industrial workplace. Main sources of community noise include road, rail and air traffic, construction and public work,
and the neighborhood.
Typical neighborhood noise comes from live or recorded music;
from sporting events including motor sports, playgrounds, car parks
and from domestic animals such as barking dogs.
Occupational Noise There are many sources of noise is industrial machinery and
processes which include: rotors, gears, turbulent fluid flow, impact
processes, electrical machines, internal combustion engines,
pneumatic equipment, drilling, crushing, blasting, pumps and
compressors. Furthermore, the emitted sounds are reflected from
floors, ceiling and equipment
Aircraft Noise Pollution Noise from Aircraft flying over residential areas impairs people's
ability to work, learn in school and sleep, and consequently also
results in lowered property values in affected areas.
As passenger volume increases and new and larger airports are
built, noise is becoming even more of a concern.
Roadway noise pollution Roadway noise is the collective sound energy emitting from motor
vehicles.
In the USA it contributes more to environmental noise exposure than
any other noise source, and is constituted chiefly of engine, tire,
aerodynamic and braking elements.
In other developed countries as well as developing countries,
roadway noise is expected to contribute a large share of the total societal noise pollution.
Under water noise pollution (UNP) UNP is intense human-generated noise in the marine environment. It
is caused by use of explosives, oceanographic experiments,
geophysical research, underwater construction, ship traffic, intense
active sonars and air guns used for seismic surveys for oil and related activities.
Constructions The noise from the construction of highways, city streets, and
buildings is a major contributor to the urban scene. Construction
noise sources include pneumatic hammers, air compressors,
bulldozers, loaders, dump trucks (and their back-up signals), and
pavement breakers.
Problem caused due to noise
pollution
There are about 25000 hair cells in our ear which create wave in our
ear, responding to different levels of frequencies.
With increasing levels of sound the cells get destroyed decreasing our ability to hear the high frequency sound.
Law governing Noise Pollution in
India
Noise Pollution (Regulation and control) Rule 2000 :-
section 3 of the Environmental Protection Act of 1986 led to Noise
Regulation Rules (2000) . The EPA is the umbrella legislation to deal with the every dynamic issue in relation to environmental protection. The
rules regulate noise levels in
Industrial, [75 decibels]
Commercial [65 decibels]
Residential zones [55 decibels]
zones of silence (100 meters) near schools, courts, hospitals, etc.
Law governing Noise Pollution in
India
The rules also assign regulatory authority for these standards to the
local district courts. Some important observations from the rules:-
• No permission can be granted by any authority for use of public address system in the open after 10.00 PM and before 6.00 AM. No
exception is possible
• After permission has been procured the sound must fall within the
sound limits prescribed in the Noise Rules. This can be measured on
a sound meter. Any person violating the Rules is liable to be arrested
under the provisions of the EPA.
Law governing Noise Pollution in
India
• If the authorities do not act to stop violation of the Noise Rules, the
citizen who has filed a complaint can approach the Court with his
complaint after 60 days' notice and the Court can initiate prosecution
• The rules also fix different ambient air quality levels for firecrackers
and industrial activities.
Law governing Noise Pollution in
India
Noise restriction on vehicles:-
Luxury Limousine 77 dB
Small passenger car 79 dB
Miniature passenger car 84 dB
Sports car 91 dB
Motor-cycle (2 cylinder 4 stroke) 94 dB
Motor scooter (1-cylinder-2-stroke) 80 dB
What can I do to make a difference?
There are a variety of effective strategies for mitigating adverse sound levels
Persuade
Taking the help of police.
Observe car free day on 22nd of September.
Creating awareness about the ill effects of noise pollution.
Promising oneself not to be the part of pollution creator.
use of noise barriers.
limitation of vehicle speeds
alteration of roadway surface texture.
limitation of heavy duty vehicles
Conclusion Improved traffic management practices, such as one way traffic
movement, proper management of buses in the traffic stream may reduce traffic noise level to some extent. Proper noise barrier should be constructed under flyovers to mitigate the traffic noise level.
The Factories Act, 1948 does not contain a specific provision of noise control while it has been found in a number of cases that high intensities, high frequencies and intermittency of noise are the factor of annoyance for the workers.
The Central and the State Boards now exercise the powers and functions under Section 16 and 17 of the Air Act, respectively with regard to the prevention and control of noise pollution including the laying down of noise standards.
Noise adversely affects general health and well-being in the same way as does chronic stress. It adversely affects future generations by degrading residential, social, and learning environments with corresponding economic losses.
