Noise is a disturbance to the human environment that is escalating at such a high rate that it will become a major threat to the quality of human lives. In the past thirty years, noise in all areas, especially in urban areas, has been increasing rapidly. There are numerous effects on the human environment due to the increase in noise pollution.

Noise pollution can be defined as unwanted or offensive sounds that unreasonably intrude into our daily activities. It has many sources, most of which are associated with urban development: road, air and rail transport; industrial noise; neighborhood and recreational noise. A number of factors contribute to problems of high noise levels, including; increasing population, particularly where it leads to increasing urbanization and urban, consolidation; activities associated with urban living generally lead to increased noise levels and increasing volumes of road, rail and air traffic. Noise pollution can be categorized under the following sources: domestic, industrial, produced by construction works and transport.
