Noise Pollution Sources and Effects

Noise pollution refers to the disturbing, unwanted or excessive sound that disrupts our peace of mind and interferes with our daily activities such as reading, sleeping, conversations etc.

It has been established that exposure to sounds of less than 70 dB is not harmful to hearing regardless of exposure time. On the other hand, exposure to sounds of more than 85 dB for over 8 hours is potentially harmful.
