Noise pollution refers to the state of unbearable and uncomfortable to human beings which is caused by noise from different sources. In recent years, noise pollution has become a serious problem.

The following sources are mainly responsible for noise pollution:

(i) Factories.

(ii) Mechanised construction and demolution works.

(iii) Automobiles.

(iv) Aircrafts.

(v) Sirens.

(vi) Loud speakers used in various festivals.

Of all these sources, the biggest nuisance is the noise produced by traffic. Its intensity and nature depend upon the type of vehicle, trains and the condition of road as well as that of vehicle. In sea traffic, noise pollution is confined to the harbour due to loading and unloading activities being carried, creating noise.
