NOISE POLLUTION INDICES FOR KOTA CITY, RAJASTHAN (INDIA)KULDEEP, SOHIL SISODIYA AND ANIL K. MATHUR
Kota, âThe New Kashi of Education,â is a district in the south-east of Rajasthan state of Republic India. Kota, one of the largest cities of India, is gradually evolving as an urbanized and industrialized city. Noise level analysis for day time was conducted in sixteen sampling locations of four different zones/areas of Kota City viz. silence, Commercial, Industrial, and residential. Noise pollution indices such as L90, L50, L10, NC Lnp, Leq, and NEI were estimated for each zone/ area. Such data offers an understanding of noise levels, including noise level variations. It is known to be the best indicator of the physiological and psychological effects of noise on people. Leq levels of different areas/zones were compared to the CPCB Noise Pollution Guidelines. During the observation period of six days for a specific sampling location, it noticed that the Leq for day time was found in between 65-85 dB. All monitoring locations show a high variance in compliance with CPCB and a minor difference detected in the noise levels of all 16 sampling locations. NEI has been observed greater than 1 indicating more significant noise in all these sampling locations. The results of noise assessment for Kota City specifically identified the alarming level of noise pollution in Kota.
