The word “noise” has attained from the Latin word “nausea” which is known as seasickness. Noise pollution refers unwanted or excessive sound that can have serious effects on health of human body, animal and environment. Noise pollution is common inside of industrial facilities and some other workplaces, but it may also create from highway, railway, airway and from construction activities. All types of noise are responsible for hearing loss, stress and high blood pressure. A study of World Health Organization (WHO) says that noise pollution can be linked to health conditions such as cardiovascular disease, disturbance in sleep tinnitus, children’s cognitive impairment and annoyance. Along with the increasing degree of air and water pollution, the inhabitants of Dhaka city are being exposed to high level of noise pollution. Its main reasons are urbanization and motorization. The hazard of noise pollution increased and exceeded its tolerable limit with the increasing number of motorized vehicles in the city. Although there are many other sources of the level of noise pollution is very closely related to urbanization and motorization. Most of the outdoor noise pollution is due to transportation system, including noise of motor vehicle, aircraft and rail [6]. This happens due to Poor urban planning like as side-by-side industrial. The hearing ability of the inhabitants of Dhaka City has reduced during the last ten years. About five to seven percent of the patients admitted to the Bangabandhu Sheikh Mujibur Rahman Medical University (BSMMU) Hospital, Dhaka is suffering from permanent deafness due to noise pollution.
