Abstract:
Noise is an unavoidable part of modem life. It is well established now that noise is a
potential hazard to health, communication and pleasure of social life. This problem is not
pertinently acknowledged despite the fact that it is steadily growing in developing
countries. Noise pollution is one of the main causes of environmental pollution in
Narayanganj, yet much of the noise is unnecessary.
The present study reveals that most of the traffic points and many of the industrial,
residential, commercial, silent and mixed areas of the city are suffering noises exceeding
the standard limits of Bangladesh. Study found noise levels of 76 dB at Chashara, 56 dB at
Masdair, 79 dB at Khanpur Industrial area, 58 dB at Khanpur Hospital, and 62 dB at
Tanbazar during weekdays though the standard limit for those area are 70, 50, 75, 45 and
60 dB respectively. Required actions include enforcing existing laws on noise pollution,
totally outlawing the use of miking for processions and advertising, prohibiting industrial
activity in urban areas, introducing and enforcing limits on decibels in urban areas,
improving traffic system, and raising consciousness among people.
