Sound / Noise quality Audit
A sound or noise audit examines noise levels in any premises. Noise can cause ill health effects as well as socio-cultural and economic effects. In most of the cases the long and short term effects cannot be evaluated objectively.

Noise is generated from various sources. The increasing ambient noise levels in everyday life is due to various industrial and commercial activities, fire crackers, sound producing instruments, generator sets, loud speakers, public address systems, music systems, vehicular honking and other mechanical devices have deleterious effects on human health and psychological well being of the people.

It is considered necessary to monitor, regulate and control noise producing and generating sources with the objective of maintaining the ambient air quality standards in respect of noise.
