Acoustic pollution is disturbing noise with harmful effects on the activity of human or animal life. The source of worldwide noise worldwide is mainly caused by machinery and transportation systems, motor vehicle engines and trains. Environmental noise is summed up in ambient noise. Poor urban planning can generate acoustic pollution, industrial and residential buildings side by side can generate noise pollution in residential areas. The documented problems associated with the noise of the urban environment go back to ancient Rome. Road noise and other urban factors can be mitigated by urban planning and better road design.
Outside noise can be caused by machines, construction activities and musical performances, especially in some workplaces. Noise-induced hearing loss can be caused by external noises (eg, trains) or interior noises (eg, music). High levels of noise may contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering the detection and avoidance of predators or dams, interfering with reproduction and navigation, and contributing to permanent hearing loss.
