REMOTE SENSING BASED NOISE LEVEL ASSESSMENT: A CASE STUDY OF COIMBATORE CITY, INDIAE. Sarojini, S.D. Anitha Selvasofia S. Kanchana and B. Kamal
Major cause of noise pollution is the improper design of city with mixed zones. Normally a city is defined by four major zones namely: Commercial, Industrial, Residential and Silence Zones respectively. The noise pollution occurs due to traffic and transport and when industrial zones mix up with residential or silence zones. So, noise pollution can be controlled efficiently when construction or progress of buildings are within their respective zones. Study area, Coimbatore is the largest non-metro city in India reported to face frequent noise pollution issues. It has many industries (Textile, Foundry, pumps etc), within the city and many of the industries are clubbed together with other zones as mixed. Noise monitoring is carried out in the city by dividing the city into five major regions. The important places of each region were monitored during regular time intervals (peak hours). The modelling of the localities predicts the Noise impacts in the form of map using the ArcGIS software. The summation of recorded noise levels gives the prevailing noise in the place, and helps to identify the risk areas. The results demarcate the considered regions into regions where noise level are within limits and regions where noise exceeds. The control methods are suggested to be implemented in the affected areas.
