Whole day sound pollution data was recorded by using digital sound recording meter on different dates. Important city road intersections, schools,colleges and hospitals, bus,truck and launch terminals, residential and commercial areas were the sampling points. All these thirty two locations had intensity of sound far exceeding the allowable limit of : 50 dB in tranquility zone like school and hospitals, 55 dB in residential areas, 70 dB in commercial area and bazaars, 60 dB in mixed areas. Kaptai Rastar Matha had the worst result; sound intensity exceeding 100 dB in peak hours.

In general, all most all these locations had sound intensity exceeding 80 dB in peak hours. Prolonged exposure to annoying sound in the range of 80 dB may cause permanent damage to hearing ability. Physical, physiological and psychological damage to human being are expected in such situation. This is an issue which demands serious attention from the city dwellers and the policy makers.
