Walkman, concerts, disco, playing music … The intense sound sources are ubiquitous. Your child must learn to listen to music responsibly to protect his hearing. Educate him and give him good advice.
The hearing is increasingly common among young:
Hearing particularly affect older people, but there is that young people are increasingly likely to suffer from hearing. About 10% of fewer than 25 have a hearing loss, whose main cause is noise exposure. Is that exposure to intense noise, prolonged or repeated, is likely to cause serious injury, premature and final. And sources that young people are exposed are numerous, pervasive and often intense, from the player at high volume, concerts and nightclubs, from those who play music. Thus 57% of youth 15-30 years have already experienced hearing for the release of a concert or a nightclub. Surprisingly, only 7.5% wear hearing protection (ear plugs) and only 5% away from noise sources.
The signs to take very seriously:
Humming, whistling, feeling cottony ears and hyperacusis (increased sensitivity to sound), are all symptoms that should lead away from the noise.
If they persist for several hours or after a night of sleep, in consultation with an ENT urgent need, otherwise go to emergencies. Attention, the pain is not a criterion. The threshold of danger to the ear is 85 decibels (dB) and is equivalent to the sound of a lawnmower, while the threshold of pain is 120 dB (equivalent to the noise of an airplane engine).
In practice, recommend that young to limit the amount and duration of the listening device. Do not put the volume at half the maximum volume (one player to maximum volume is 100 dB, which is equivalent to the sound of a jackhammer). If listening is done at a higher volume, it is imperative to limit listening to a few minutes.
Prefer listening with headphones rather than ear. The helmet insulates better noise surrounding this that encourages less to mount the volume. Regarding the atria, using those supplied with the camera because they guarantee a maximum sound level of 100 dB.
If a person within one meter of you heard your music player is that the volume is too loud. In concert, wear ear plugs. Then wait to be calm before withdrawing. Disco, make very regularly breaks: 30 minutes every 2 hours or 10 minutes every 45 minutes.
Namely
Pitched tones is more dangerous to the ear that his grave. A sudden and unpredictable son is more harmful than continuous. We are not all equal in relation to sound; some people are more vulnerable to noise exposure particularly in the event of medical history as ear infections.
The ear does not get used to loud noise, the brain adapts messages sound. Attention alcohol and drugs can distort the auditory perception (impression that the sound level is less than reality).
