An increasing trend of noise pollution has been observed in the major cities of the
country. To regulate and control noise pollution, the Government has issued various
notifications under the Environment (Protection) Act, 1986. During the year noise limits for
diesel generator sets (upto 1000 KVA) manufactured on or after 1st July, 2003, were notified
on 17th May, 2002. The maximum permissible sound pressure level for new diesel generator
sets with rated capacity upto 1000 KVA shall not exceed 75 dB(A) at the distance of one
metre from the enclosure surface. It has been made mandatory for the diesel generator sets to
provide integral acoustic enclosure at the manufacturing stage itself. The State Pollution
Control Boards and the Pollution Control Committees will regulate these limits.
A Notification on Noise Pollution (Regulation and Control) Rules, 2000 was issued vide
S.O. 123(E) on 14th February, 2000 to curtail noise pollution in the country. Accordingly, the
use of loudspeakers and public address systems were restricted during night between 10.00
p.m. and 6.00 a.m. except for the closed auditorium, banquet halls, etc. Owing to various
representations received from State Governments, these rules have been amended vide
Notification S.O. 1088(E) issued on 11th October, 2002 to permit the use of loudspeakers or
public address system during night hours (between 10.00 p.m. to 12.00 midnight) on or
during any cultural or religious festival for a limited duration not exceeding 15 days in all
during a calendar year.
Noise limits for vehicles at manufacturing stage were notified vide GSR 7(E) on 25th
September, 2000 which would be effective from 1st January, 2003. To make these standards
commensurate with the emission standards for vehicles, the notified rules have been revised
and are phased out in two stages. In the first phase, two wheelers, three wheelers, and
passenger cars would comply with the notified norms from 1st January, 2003. A relaxation of
3dB(A) has been given to passenger and commercial vehicles of various categories and
would become effective from 1st July, 2003. In the second phase, noise limits for vehicles at
manufacturing stage would be applicable on and from 1st April, 2005 which would be at par
with EC norms and based on engine power for various categories of vehicles.
Hon’ble Supreme Court, in September, 2001 has passed an interim order to comply with
the notification of the Ministry issued on 5th October, 1999 to control noise from the bursting
of fire crackers, which shall not exceed 125 dB(AI) and 145 dB(C)pk. The manufacture, sale
and use of fire crackers should be restricted accordingly. While communicating this order to
all State Governments and Union Territories, they have been requested to conduct the surveys
to assess the noise pollution before and on Deepawali day. Some of the surveys have been
conducted during the years of 2001 and 2002. The findings of the surveys indicate a
decreasing trend of noise during the festive season.
For creating awareness and for effective implementation of the rules and regulations for
control of noise, a workshop was organized at West Bengal Pollution Control Board on 4th
and 5th December, 2002 to train the officials of State Pollution Control Boards and the
officials of Police Department of Eastern States.
