Myths and facts


Sound ear frequencies can be heard from 20 to 20,000 Hz, however, some sounds can cause permanent or long-lasting hearing loss. This hearing loss occurs immediately or after prolonged hearing of sounds at very high levels of sound. The sound is measured in decibels (represented by “decibels”).

An average conversation size between two people, for example, is 60 dB, which is too low to cause damage. For example, too, the average rock concert averages about 120 decibels, causing hearing damage in the first 15 minutes. Quite simply, the lower the volume, you can listen to it over time without the risk of damaging your hearing; the higher the volume, the faster the hearing damage

Nowadays, there is noise all around us. In urban or remote areas, the sound level can reach critical levels. Although most people are generally aware of some of the dangers of hearing noise, many myths about noise hearing loss remain. Below are some explanations in addition to the dB standards resulting from our current environments


Noise is harmful only when it is too high over a long period of time

Noise can be harmful if it is: strong and over a long or strong and sudden.


People with hearing loss can regain full use of their hearing abilities.

Even if they stay away from the  noise and show close interest in their surroundings for an extended period of time, this belief will unfortunately remain  wrong.  Hearing is    irreversible because the cells lining the ears are not renewable.


Hearing protectors help maintain hearing of hearing loss

In fact, adequate hearing protection with each person’s needs will reduce the intensity and strength of the harmful noise surrounding   it.


The noise is dangerous if I have to scream until I hear because of the background noise. hearing loss

The fact that having to scream to hear your voice is an indication that the noise around    you is dangerous.
