Noise pollution or sound pollution refers to the
dangerous and unwanted level of disturbance
caused by noise. Noise is measured in
decibels or dB, A sound more than 85db is
said to be a damaging level of sound that,
over time, can causing hearing loss. Noise
pollution is a problem faced all over the world,

There are numerous sources of noise
pollution. One of the primary causes is
industrialization, especially in urban areas.
Industries use heavy equipment such as
generators, compressors, mills, etc. that make
high pitched sounds that are very unpleasant
and cause a disturbance. Road traffic is
another major contributor to noise pollution.
Increased transport of cars, motorcycles,
trucks, etc. have to lead to increased noise
disturbance on the road.

Construction of roads, buildings, apartments,
highways, etc, uses heavy equipment such as
excavators, compressors, hammers, etc.
These create a lot of noise, causing
disturbance to its surroundings. Poor urban
planning such as congested living spaces,
large families living in a small area, parking
spaces, etc causes many fights as they are
competing for the same resources. The use of
firecrackers during festivals is also a source of
noise pollution. These crackers generate very
high pitched and sudden sounds. They are
contributing to noise as well as air pollution.
Another source of noise pollution includes
playing loud music, especially during social
events like marriages. Low flying aircraft of
the military also cause noise pollution. Ocean
sound pollution is caused due to submarines
Other sources of noise pollution include.
household equipment, air conditioners,
kitchen appliances, etc.

Noise pollution primarily affects a person's
hearing, leading to hearing impairment to even
permanent loss of hearing. It causes an
increase in blood pressure, hypertension.
fatigue, and cardiovascular diseases. Noise
pollution also disturbs a person's state of
mind causing disturbed sleep patterns, stress,
aggressive behavior, decreased concentration,
and poor quality of life. Noise disturbance is
extremely dangerous to elderly people and
pregnant women.

Noise pollution also ariete and
marine life. Animals have a more advanced

hearing. Noise pollution can impact their
listening skills and cause changes in their
behavior, starting with a pet at home. It leads
to changes in their hearing due to which their
communication also becomes affected. They
are unable to hear properly during migration
as they require sound to find their way. Noise
pollution also affects crop production. Ocean
sound pollution causes internal damage such
as cardiovascular problems and physical
problems such as hearing impairment in
marine life. They are forced to leave viable

habitats.

There are noise pollution preventive measures
available, Soundproof walls and windows are
one way to prevent noise pollution from
entering the premise. Faulty equipment must
be checked and repaired regularly. Needless
honking must be discouraged. Many hospitals.
and schools are silent zones to ensure that
disturbance does not occur. Rules to prevent
noise at certain hours are in place, which
many governments have implemented. Using
earplugs and switching off appliances when
not required, can also help. Planting trees can
also help as they absorb noises. International
Noise Awareness Day is witnessed every year,
usually on the last Wednesday of April. This
day was marked on April 29 in 2020.
