Noise is characterized as unwanted and bothersome, qualities that make a person particularly receptive to it. Auditory pollution does not directly cause immediate server damage, except in extreme cases like in explosions or sounds of extreme loudness. Nevertheless, the deteriorating mental health of the population and the increasing number of nervous related sicknesses, makes noise a main focus in the cause of environmental pollution. Noise changes one's concentration, work and thought productivity, ability to rest, and in high doses, produces irreparable auditory damage. In the workplace environment, persons exposed to high levels of noise are susceptible to sever hearing loss or deafness, which makes them more susceptible to noise outside the workplace.
Statistics show that Sensorineural hearing loss is one of the most common workplace sicknesses.
In the environment outside the workplace, the most important manifestations of noise are undoubtedly in the cities, places in which the majority of activity and people are found, and therefore a large number of affected people. There are big differences between noise and other pollutants. One of its most important characteristics is its complicated enforcement. This underestimates its effect, which is different from other pollutants. Water pollution, for example, is seen, smelled, and tasted.
