In modern megalps, the noise level annually increases by about 1 dB. In Moscow, the zone of acoustic discomfort is distributed by 30% of the area of the city, and the noise level exceeds the remote control (maximum permissible level) by 20-30 dB.
Noise near Moscow trails reaches 80-90 decibels. In addition, industrial enterprises are used by the sources of urban noise, among which energy installations (100-110 dB), compressor stations (100 dB), metallurgical plants (90-100 dB), etc. Employees are risking to get the hearing loss or inflammation of such industries nerve.
With systematic effects of high noise, the rumor decreases after 1-2 years, with an average of 5-10 years. For example, a regular stay in places with a noise level of 85-90 dB (this, we recall, fixed near the metropolitan automotive) leads to a gradual decrease in the hearing sensitivity, primarily at high frequencies. For a long time, a person complains about malaise: headache, dizziness, nausea, excessive irritability ...

Hello, do you hear me?
Just as noise is the cause of not only auditory disorders and auditory disorders are often caused not only by noise. Doctors highlight some more risk factors for the development of hearing loss. For example, the use of headphones and intraphic phones (in this case, sound oscillations are not "filtered" the outside ear, which leads to functional changes in hearing). Another risk factor is the effect of electromagnetic radiation (AM). Amy accompanies the work of all electronic devices, but mobile phones have the most negative impact on the rumor.
Headowness can be caused even by changing the nature of nutrition. For example, if a person sits on a carbohydrate diet, it can lead to changes in small vessels, which, in turn, leads to a deterioration in the nutrition of a hearing receptor, and, as a result, a decrease in hearing sensitivity.
In addition, it is necessary to take into account that in our body everything is interconnected. And if the load increases, for example, on vision, the load and hearing receptors are automatically growing. This happens when working on a computer - eyes redirectly, and at the same time, the ears are imperceptibly "for two".
