hearing loss & Noise-induced
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.
In this context, how do you navigate between ambient noise and what guidelines for respecting the health ofyour hearing? It has been shown that hearing damage may arise during 8 hours of exposure to noise exceeding 75 decibels.
Here are the ranges of sounds that can damage your hearing
85 – 100 dB
(About6 to 8 hours can cause damage)
- Heavy traffic
- Window air conditioner (close to you)
- Noisy bar
- Subway/Train Transit
- Listen to music with the fullest sound
110 – 180 dB
(A minute can cause damage)
- Emergency car sirens
- Balloon explosion (near the ear)
- Take-off/landing of the aircraft
