Assessment, Analysis And Evaluation Of Noise Level Of Steel City Rourkela

摘要

In this present study, an attempt is made to estimate and analyse noise pollution level at different areas of steel city Rourkela, Orissa and the health hazard effect produced by it. We measure the noise level at sixteen different places within the city at different time intervals. The different descriptors, like traffic noise index, noise climate, L_(eq), noise pollution level, L_(day), L_(evening), L_(night), L_(den) are calculated and the calculated data obtained is much beyond the permissible limit (in the day time, it is 70 dB and in the night time is 59 dB). The increase in noise level at different places is primarily attributable to motor vehicular traffic, marriage and festival season noise and industrial noise of Rourkela Steel Plant (RSP) alongwith many small and medium scale industries. The noise levels of most of the analysed area exceed the permissible limit during day time. The different vehicles that contribute to increasing the noise level are heavy engine, trucks, tractors, dumpers, motorcycles, night coach buses, pickup van and tempo, etc. This study gives certifications for consideration of all forms of people affecting the problem of noise pollution in the steel city Rourkela, Odisha.
