The source of outdoor noise worldwide is mainly caused by machines, transport and transportation systems.[1][2]Poor urban planning may give rise to noise pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. The main sources of noise in residential area are loud music and loud barking by domestic dogs. It can also be loud talking or shouting by humans although this last is less persistent. Noise pollution associated with household electricity generators is an emerging environmental degradation in many developing nations. The average noise level of 97.60 dB obtained exceeded the WHO value of 50 dB allowed for residential areas.
