The document classifies noise pollution into three main types: industrial, transport, and neighborhood noise. Industrial noise comes from machinery in factories and construction sites. Transport noise is caused by traffic and vehicles. Neighborhood noise includes noise from appliances, loud speakers at events, and human activity. The document discusses the health impacts of noise pollution and legislation to regulate noise levels in different areas.

THE SILENCE BEHIND NOISE POLLUTION

5.  Industrial noise is caused by some high intensity
decibels that is the result of industry machines
and other such appliances. The noise comes from
the use of mills, heavy industrial machines and
even the small exhaust fans that run for a long
period. Noise from mechanical saws and
pneumatic drills is unbearable and the ultimate
form of pollution to the public and
neighborhood. This is one cause of noise
pollution. Industrial areas, the permissible limit is
75 dB for daytime and 70 dB at night.

7.  Transport noise is simply inevitable. The
traffic jams cause considerable amount of
vehicle noise and the honking of the many
vehicles in the crowd are nothing but a pure
nuisance. Whether road, rail or aircraft, their
noise is a considerable contributor to noise
pollution. Tractors and other heavy vehicle
sounds are difficult to control for their sound.

10.  Gadgets, electrical appliances like the
grinder and mixer are the prime
contributors to noise pollution. Loud
loudspeakers in the name of wedding,
political parties and other such events call
for a significant amount of noise pollution.
In the long run, they become difficult to
bear posing problems to the health of
humans.
 And no! Humans are the not the only ones
to get affected. Marine animals also suffer a
disturbance in their cycle. Some of these
types of noise pollution cannot be really
controlled for and calls for other ways for
us to take care of ourselves.

11.  The Indian Institute of Oto-Rino Laryngology,
Chennai has reported that increasing
industrial pollution damages the hearing
ability by at least 20%.
 Workers in steel industry, who work close to
heavy industrial blowers are exposed to
112dB for eight hours suffer from
occupational pollution. This a bad sign.
 In commercial areas, it is 65 dB and 55 dB,
while in residential areas it is 55 dB and
45 dB during daytime and night respectively.
