Noise pollution is one of the popular types of pollution nowadays. The definition of noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. Noise pollution is the result of the noise of machine and transportation systems, motor vehicles, aircrafts, and trains. Although noise contamination doesn't cause some serious effects like air pollution, water pollution, or soil pollution, it also had bad impact on human life. In a high level, noise disturbance can contribute to cardiovascular effects in human and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.
