If a child, a spouse or other loved one has become worse to hear, you can easily define it yourself.Initial signs are simple: he did not immediately respond when his name was often asks, much louder than usual includes a TV and radio, even when it does not sound like the music, and the usual speech, complaining of pain in the ears, constantly hears ringing or knocking.Complement these unpleasant symptoms can be dizziness, headaches and constant fatigue.All this is a reason to seek immediate medical attention otolaryngologist.Let's talk about the signs of hearing loss in humans.
In medicine, there is such a thing about the signs of violations as "acoustic trauma" - damage to the inner ear due to loud noise.The cause of chronic acoustic trauma can be a permanent effect of noise and vibration at work or military trials - is if the noise source is at a fairly large distance from the ear, but its effect for a long period or permanently.But an acute acoustic trauma - is when a sound wave strikes with force (
After striking distance of the acoustic wave to the ear of the eardrum when wearing the headphones - just 1-1.5 cm, and the time it is carried out in headphones, most teenagers and many adults, too, often exceed the eight-hour day in a noisyproduction.A vicious circle: the longer a person is listening to loud music, the worse he hears.And worse, he hears, the louder he has to include the sound of the music player.Young people working self-healing mechanism of hearing, but this is possible only in case of failure from constant exposure to sound.
Headphones also are different in the appearance of a violation - and full-size plug.From the viewpoint of doctors, the first bit still safer.Why is that?From plug headphones sound is fed directly into the ear canal, bypassing the natural cavity - the outer ear, and hits right at the eardrum.Distance of the acoustic wave hitting her on the minimum air pressure is very strong, pressure drops dramatically.With Earphones most likely to produce an acute acoustic trauma, for example, if you listen to the radio and all of a sudden after the song at high volume includes advertising.In addition, they contribute to the formation of plugs in his ears: mechanically driven stand-sulfur back into the ear canal.As a result of reduced hearing, and the person making the music louder and presses the headphones even tighter.
way, psychologists and psychotherapists are concerned about harm headphone no less otolaryngologists.It turns out that the constant listening to music - it is the same relationship as, say, gambling or smoking.A man is literally transferred from the real world to the other, full of beautiful sounds and images.Connects imagination, he gets used constantly enjoy.
Consequently - hundreds of thousands of people who are unable to work or relax, or even fall asleep without accompanying noise and, therefore, and headphones.The higher the degree of dependence, the more time a person spends "with music in the ears" and, in fact, partly in a parallel dimension.In this state, he can not feel neither the time nor the distance, his attention is scattered, the ability to concentrate is reduced, although many argue that only the player can prove complicated trigonometric identity or write a term.
But what they really easily - it is, for example, become the victim of the attack, get hit by a car or a train.Statistics inexorable: almost all fall under train people just have not seen or heard her approach and did not pay attention to the signals, because they were wearing headphones.
