C. Ambient Noise Standards: Ambient standard with respect to noise have been notified by the Ministry of Environment and forest vide gazette notification dated 26th December 1989(amended in February 2000). It is based on “A” weighted equivalent noise level (Leq). The ambient noise standards are presented in table below: Ambient Noise Quality Standards Limits in dB(A) Leq Area code Category of Area Day Time Night Time A Industrial Area 75 70 B Commercial Area 65 55 C Residential Area 55 45 D Sensitive Area 50 40 Note: *Day time is from 6 am to 10 pm, Night time is 10 pm to 6.00 am; ** Silence zone is defined as area up to 100 meters around premises of hospitals, educational institutions and courts. Use of vehicle horns, loud speakers and bursting of crackers are banned in these zones. D.
