The noise level measurement was carried out to assess the traffic generated noise in Angul Town Campus during the month of March 2015 and April 2015. Extech's Datalogging Sound Level Meter (model 407764) was used to measure the noise level. In the present work twelve locations were selected for the study. The measurements of noise levels at the building facades were carried out in three different time intervals of the day i.e. in the morning 8-10am, midday 11am-1pm and in the evening 6-8pm. The instrument was set to record noise samples at 2 sec intervals during the 10 minutes of exposer time. Equivalent sound pressure level (Leq), noise climate (NC) and noise pollution level (Lnp) were computed for statistical analysis of noise level. The present study reveals that the noise levels exceed the prescribed noise standard set by the Central Pollution Control Board, India (CPCB, 1998). The results of the analysis suggest that the maximum equivalent noise level was in the morning 9-11am and minimum in the midday at 11am-1pm.
