A reconnaissance of 'traffic noise pollution in the city of Patna'.

Abstract

The noise generated from traffic is a major source of environmental pollution, which is substantiated by the results of continuous monitoring of equivalent noise levels (Leq) at a number of sensitive, residential, commercial and industrial areas during day and night in 1999. The existing noise pollution status of Patna urban environment with emphasis on objective measurement is reported. The data were compared with the published data of other towns and cities and the possible factors responsible for change in the noise levels are discussed.
