Abstract: Now a day’s noise level has been increased due to increasing of urbanization, industries and vehicles. Assessment of noise levels was conducted in various places at day time with working condition. The selected spots are manufacturing laboratory, thermal laboratory, electrical machines laboratory-I, electrical machines laboratory-II, CAD laboratory and construction site. Those selected areas were surveyed and noted the noise levels in day time with working condition. Minimum 5 readings were measured in each areas and found mean value of areas. All measured values were recorded. The sound level meter was used for measure noise levels. All readings were subjected to statistical analysis. Maximum and minimum noise levels measured in laboratories and construction site at day time forenoon 3 hours and afternoon 3 hours, totally 6 hours. Those noise levels compared with OHSAS standards. Noise pollution was finally concluded, it was higher at day time in construction site and lower in CAD laboratory.

Keywords: Noise pollution, Laboratories, construction site, OHSAS.
