The concept of Noise pollution is a very current concept that has to do with the problematic phenomenon that develops especially in large cities and that implies the generation from levels very loud noise or sounds that can be harmful to the Health and the hearing well-being of a person who is constantly exposed to them. The contamination Hearing has to do in most cases with sounds and noises that occur in the public sphere and that are caused by phenomena such as traffic and vehicle horns, the constant activity of airplanes and other aircraft, the presence of public works that use power tools very sound, etc.

According to the World Health Organization (WHO), it is considered that the levels of exposition the sound of a person should never exceed 70 decibels. This is so since it is considered that the human ear can tolerate and assimilate that level of sound without being temporarily or permanently damaged. Any sound that is calculated above that volume Sound will be considered dangerous and possibly cause some kind of injury to the person, especially if that person is constantly exposed to sound.

Many times, a person can temporarily lose their hearing if they were suddenly exposed to a very high pitched sound. This is the case with exposure to noise bombs, fireworks and other types of particular explosions. However, in many of these cases, hearing can resume some time later since, being an isolated situation, the human auditory system is not completely damaged.

However, permanent exposure to sounds close to or above 70 decibels can cause serious damage to a person's ear as the injury does not have time to heal and is still aggravating. In most cases, the damage that this type of noise pollution generates is imperceptible and gradual, so the person does not act to stop it. The person can also suffer from insomnia and fatigue, irritability and stress due to this type of sound exposure.
