Navsari, a middle level city in South Gujarat with a population of 1,60,100 compared to 1,34,017 of 2001, was selected to study the noise pollution. The city on the banks of river Purna is approximately 25 km from Surat, the fastest growing city in India. Just a few decades back, Navsari was considered as a small satellite town of Surat, but with rapid industrialization and urbanization numbers of vehicles have increased significantly. The decadal population growth for Navsari district recorded in 2011 has remained 8.24 percent whereas it was 13.24 percent during 1991-2001, on the contrary vehicular population, as per the vehicles registered at Regional Transport Office (RTO), Navsari, recorded 371 % growth over the previous decade, mopeds and scooters registered 357 % increase and motor cars 515 % increase over the previous decade. Noise pollution survey was conducted at various locations of the city at different timings for different duration with a portable sound level meter. Values indicate that noise pollution level in the study area varied between maximum of 107 dB and minimum of 32.1 dB. The Leq values clearly show that noise pollution levels are much higher than the prescribed (by Ministry of Environment and Forestry and CPCB) limits in all locations except within the Agricultural University campus, the reason being that only limited numbers of vehicles are permitted to enter the campus and a good share of vegetation helps in absorbing noise
