The study reports the analysis and measurement of the noise levels of CNG refueling Stations and\nPower Generators of Power Development Board (PDB) induced noise pollution in Sylhet City. For this\npurpose noise levels have been measured at ten major locations of the city for CNG refueling Stations\nand in PDB, Kumargaon. Sound levels are measured at different location at different time interval for\nthe respective study locations with the help of a standard Sound meter. It was found that the noise\nlevels for both study locations are much higher that exceed the allowable permissible noise limits. The\nstudy suggests that noise path must be controlled by using appropriate sound barriers that can reflect\nand diffuse noise appropriately and particularly use of sound enclosure can reduce noise level
