ABSTRACT
Environmental noise is an unwanted and undesirable byproduct of industrialization and urbanization that causes disturbance. Many people struggle to comprehend noise as a physical contaminant. This is because a rise in noise level is difficult to notice because the human ear automatically adjusts to the noise level. Numerous negative consequences, including deafness and mental collapse, may result from rising noise pollution. It is, therefore, necessary to assess the environment where noise levels have risen and analyze it to determine whether a definite disturbance exists. Natore City is one of the old cities of Bangladesh. It is rapidly emerging as an industrialized and urbanized city as it is located near Rajshahi, which is seriously affected by this phenomenon. This study aims to reveal the growing level of noise pollution in Natore City, Bangladesh. During the working days, the noise level measurements were conducted using a digital noise level meter in five different zones from 9 AM to 12 PM. It was seen that the measured noise level of the residential area of six points exceeded the acceptable limits recommended by the DoE. All study points of the educational area crossed the allowable limit. However, eight study points of the commercial area were above the acceptable value recommended by the DoE. The central part of Natore City was less polluted than the eastern and western parts of Natore City. This study also suggests the necessary measures which may be taken to keep the sound level within an acceptable limit.
