There is very little demarcation of sound and noise. Sound is a normal phenomenon of life while noise is nothing but unwanted sound. Therefore, noise pollution is unwanted sound, dumped into the atmosphere without regard to the adverse effects it may have. Encyclopedia Britannica defines noise pollution thus β€œIn acoustics noise is defined as any undesired sound. According to this definition, a sound of church bells may be music to others. Usually, noise is a mixture of many tones combined in a non-musical manner.

βœ’ ANSWER
Normal level of the sound is necessary to maintain the daily lives however undesired sound or noise which is not tolerated by the people, animals or plants causes noise pollution in the environment. Noise is commonly called as the unwanted sound created by many industrial or non-industrial sources used in the daily life in our surrounding. High level sound creates unpleasant effects and discomfort to the health especially to the ears.

Unwanted sound generally interferes with the daily routine activities like sleep in night, conversation, hearing ability, feeling of well being, etc. Water animals are also affected by the noise pollution created by the noise of submarines and big ships in the ocean. Forest animals have been affected to a great extent due to the chain-saw operations (create extreme noise) by timber companies. Common sources of the noise pollution are household gadgets, transport vehicles, jet planes, helicopters, industrial machines, etc. According to the World Health Organization, industries must limit their sound production by 75 dB.
