Generally, Noise Pollution Is Described As Constant Exposure To Elevated Sound Levels That Can Cause Harmful Effects On Humans And The Environment. Noise Levels Below 70 Db Are Not Giving Any Adverse Impact On Living Organisms, Regardless Of How Long Or Consistent The Exposure Is.

The World Health Organization Has Recommended That The Highest Permissible Limit Of Noise Exposure In The Workplace Is 85 Db For Maximum Exposure (8 Hours A Day).
