The unwanted noise which is harmful for human health and which affects nature is called sound pollution. The capacity to listen and tolerate noise differs in case of different people of varying age.
Youth in the age group of 15 to 25 years contribute more in causing noise pollution.

Most nations have prescribed minimum and maximum tolerable sound pollution levels. Places like bedrooms and hospitals must have lowest noise levels. We must try reducing sound pollution.
For this, we need to adopt following measures:
Dense growth of trees absorbs noise and reduces sound pollution. Therefore trees like neem (Indian Lilac/ Azadirachta indica), banyan, peepal (sacred fig/ Ficus religiosa), tamarind should be planted on both sides of roads.
We must use earplugs or put cottan balls in ears while at places where noise levels are high.
Use of sound absorbing machines is advisable.
Battered vehicles, vehicles like trucks which produce high amount of sound should not be allowed to ply in residential areas and vehicles must have efficient silencers.
Horns producing loud sound should not be installed in vehicles.
Mechanical industries should be set up at a distance from city.
Growth of population must be controlled.
We must use bicycles or walk down to travel short distances. If possible we should travel by buses or share vehicles to reach work place instead of using separate vehicles.
Volume of radio, tape recorder, television etc should be kept low.
If you are listening to radio or music system alone, use of earphones is advisable.
We must do away with the tradition of using loudspeakers and causing sound pollution on occassions like elections, marriages, festivals etc.
What is most important for us is to be wary of sound pollution and curb it whenever possible.
