Noise Pollution,Sources,Causes,Effe cts,Control of Noise Pollution!! NOISE POLLUTION Noise pollution or sound pollution is defined as the unwanted sound dumped into the atmosphere that leads to health hazardous. SOURCES OF NOISE POLLUTION 1. Transportation system is the main source of noise pollution in urban area. 2.

CONTROL OF NOISE POLLUTION 1. Planting bushes and trees in and around sound generating sources is an effective solution for noise pollution. 2. Regular servicing and tuning of automobiles effectively reduce the sound pollution. can 3. Building can be designed with suitable noise absorbing material for the walls, windows and ceilings. 4. Worker should be providing with equipments such as ear plugs and earmuffs for hearing protection. This is the general idea of noise pollution. Thank you.
