Question

Study of sound pollution in namrup industrial area ?

Answer 1

Noise has become an important aspect of urban environmental due to ever increasing urbanization. It is assuming increasing dimensions with rapid increase in the number of vehicles, industrialization and urbanization. To know the status of the noise pollution level in Jagiroad town of Assam, a study on noise pollution level has been carried out during the period between June to August 2013. Some particular areas have been selected and divided into four zones viz. (a) Industrial zone, (b) Commercial zone, (c) Residential zone, (d) Silence zone. Noise level, the said zones are collected at day time between 10am to 6pm and evening 6pm to 9pm.The observed noise level ranges are 69.6 to 88.7 dB (A), 61.5 to 89.5 dB(A), 38.7 to 59.5 dB (A) and 40.1 to 59.8 dB(A) in industrial, commercial, residential and silence areas respectively. The findings indicates that the maximum noise level is found in commercial area due to heavy vehicular movement, high traffic congestion and outdated vehicles, narrow and poorly managed roads, etc. Moreover, urban area and commercial zones are not established according to land use plan, which is responsible to noise level enhancement. The absence of proper footpaths in the commercial area leads people to sprawl on the roads, which cause frequent traffic congestions and noise pollution
