The Centers for Disease Control sets 15 minutes as "permissible exposure time" for 100 db before possible damage can occur. A 2011 report from the Centre for Science and Environment in Delhi puts busy arteries and bus stops at 100-108db with some areas going up to 125db. In Vienna, Austria, the city ranked lowest on the Index, traffic whispers along at 55db. A recent journal article that looks at India's noise pollution policy puts road traffic sound above industrial noise and construction, even.Īccording to data from India's Central Pollution Control Board (CPBC) and independent reports, traffic sound averages 100db from the street, which is approximately like the sound of a leaf blower from about three feet away– or a rock concert, but a lot less melodious. On the streets, traffic is the worst, most consistent offender when it comes to noise pollution. However, some states have enacted statutes on this subject, e.g. The decibel count flew to about 70db when airplanes roared overhead, or on a festival day, when music blasted from revelries several blocks away. Unfortunately, there is no Central legislation to control noise pollution in India till today.
