Toassess the noise levels in different locations of Jammu city, a study was conducted twice a day i.e., day (6 -9am) and night (9 pm- 6 am). The present study deals with assessment of noise pollution in differentresidential, commercial and Industrial areas of Jammu city. The noise level was measured with the help ofsound meter (SL 4010) at different locations of Jammu south, north east and west from (June 2016 to May2017). During the studyperiod, the average noise intensity at various residential sites ranges between 49.8Leq dB (A) to 68.5Leq dB (A) during day time whereas during the night time ambient noise level rangesbetween 39.66 dB to 57.3 dB. The results clearly demonstrate that the noise quality at those areas is beyond the permissible limits as specified by Central Pollution Control Board CPCB thus contributing to noisepollution. Moreover, the Leq Max values are also greater than the permissible limits. Major sources of noisepollution are vehicular transport, frequent use of horns in vehicles during the day.
