Abstract: This is a review of definition, sources and health hazards of noise. Noise is defined operationally as audible acoustic energy that adversely affects, or may affect the physiological and psychological wellbeing of people. Sources of environmental noise include machinery, mechanical devices in residential areas, road traffic, rail traffic, aircraft operations, building construction and earth works, street services such as garbage disposal, military activities, building services and noise from leisure activities. Noise is more than just an annoyance. It is a significant hazard to public health. The most clearly identifiable hazard is hearing loss. Many studies have also clearly identified noise as an important cause of physical and psychological stress which, in turn, has been directly linked with many health problems. In this way, noise is associated with many diseases, including heart disease, high blood pressure, headaches, fatigue and irritability. Noise has also been shown to disturb sleep, affect optimum physical and mental performance and interfere with children's learning and with normal development of the unborn child. It is also reported to accelerate and intensify the development of latent mental disorders, predispose to disability and even loss of life. It is concluded that there is an urgent need for concerted effort to control noise.
