On why we sometimes hear an unpleasant noise or ringing in the ears, where it can cause and how to solve this problem.
The causes of tinnitus
Tinnitus - a phenomenon that is characterized by ringing, whistling, hissing, roaring, buzzing or other stable tones that we hear in one or both ears. It can be caused by ear infections, stress, infections of the nasopharynx, hearing loss, age-related, abnormal growth ear bones, disturbance in the blood vessels and a fairly wide range of neurological diseases (multiple sclerosis, disease Meniere).
However, the most common cause of this unpleasant phenomenon - prolonged exposure to excessive noise (above 70 dB). The above reasons can also cause a partial loss of hearing.
More tinnitus can be caused by drugs - strong antibiotics and malaria pills. Medicines containing quinine, can also cause tinnitus. But if taken in small doses and for long, ringing will take place. The same effect can cause a small group of special powerful antibiotics: streptomycin, and gentamycin.
Tinnitus does not mean that you will definitely lose your hearing, but this possibility is still there.
The surface of the cochlea in the inner ear is paved with thousands of small cells that vibrate under the influence of sound waves. These vibrations are then converted into electrical signals in the hair base to form a neural feedback network, which is controlled by the brain. This neural loop allows us to discern the finest nuances of sound in tune.
When these hairs are damaged or killed by repeated loud noises, the main neurons are still remain active and send the wrong signal to the brain that there is a sound, although in reality it not.
What to do to avoid ringing in the ears
First, try not to get sick and do not bring themselves to complications. Second, take the necessary precautions when visiting concerts, night clubs or working with hammer and other noisy instruments.
You can also buy a special hearing device that is a kind of filter that removes the sounds above the border frequency. However, you can use it only with the permission of the attending physician.
Alternatively you can manually choose headphonesThat isolate you from background noise, but will not absorb all the sounds.
