People will be patient with players in ten years

If before a hearing problem often associated with old age, but now they are increasingly suffering the youth. Why spoil a rumor? How to check? What about those who can not hear? These and other questions are answered Avdienko Elena, otolaryngologist, audiologist Scandinavian Medical Center.

Elena, why people can not hear?

For some it is a congenital abnormality. To blame genetic abnormalities or it may be due to the mother during pregnancy suffered an infection. Adults who may lose their hearing because of exposure to broad-spectrum antibiotics such as streptomycin or geptomitsin.

In addition, if the load on the ears more than you need, there may come a so-called "fatigue auditory nerve." The cells were exposed to loud noise just start to die off.

— A big load — it loud sounds?

That's right. Those who are now listening to loud music in headphones — our potential patients 10-15 years. Of particular note music lovers on the subway — there is noise 85 decibels or higher, and the player sound louder. The most harmful headphones, in-ear — they are the closest to the eardrum.

Another example: young people go to concerts, discos. Go back there and realize that they have become worse to hear. The effect of such a visit is comparable to barotrauma (injury from the sudden change in atmospheric pressure), and regular attendance at concerts, of course, the impact of these injuries are cumulative. These people are also our potential patients.

Now almost everyone uses cotton buds. They can injure the ear and deaf?

It's just an urban legend. Ear arranged "correctly", in its depth is narrowing, so just stick unable to damage the nerve or the eardrum. Although I had one case where a person to clean the ear with a cotton swab was called, he abruptly put the phone to your ear with all its consequences.

— You cured him?

Yes. If time begin to heal damage to the eardrum, these injuries heal quickly enough.

Mortgaged ear — is it dangerous?

If it is laid down permanently, it is an occasion to go to the doctor. It may be that you have otitis media or cerumen, and may be a manifestation of sensorineural hearing loss. Unfortunately, the problems with the ears, we usually go to the ENT doctor at the district hospital, which diagnoses rather superficial. Imagine a doctor in the district hospital examines the patient: no sulfur, no apparent inflammation. "The ears are clean, you are all well," — he said.

Man suffers another few months, gets an appointment with a specialist and it turns out that he has an adhesive otitis media with hearing loss requiring surgical treatment. In my experience working in the Nordic health center can tell you that running cases — are not uncommon!

— Yeah … Elena, what advice would you give someone who feels that became worse to hear?

To get started go to the reception to the otolaryngologist, and it is desirable that the specialist was an experienced and has been in the hospital where there is a modern equipment for testing hearing.

— How to test the hearing?

Testing takes place in several stages: the external examination, tympanometry (examination of the middle ear), impedancemetry (Reflex) and tonal threshold audiometry — the patient has to press a button at a time when he begins to hear the sound of constant frequency with increasing volume.

Let's try to test you.

— Come on.

The results of audiometry

Look. Normal hearing — this is from zero to 25 decibels. From 26 to 45 — the first degree of hearing loss. From 46 to 55 — the second. From 56 to 70 — the third. From 70 to 90 — the fourth. More than 90 — deafness. We take the average of indicators: you have it 60 decibels — that there is a third degree of hearing loss.

We also conduct tests on the intelligibility of speech: on the volume of 60-65 decibels give and listen to the words. A person with normal hearing in this volume have yet to distinguish them. It is easiest to differ mnogoslogovye word. Shorter than the word, the more difficult to perceive sounds. So when we need to pass the word letter by letter, we use longer words. For example, "Moscow" — "Lower" to distinguish by ear is much easier than the "m" and "n."

According to the results of the audiogram and test the intelligibility of the doctor makes a prediction — can regain the ability to perceive speech.

— How to test hearing in very young children? They did not say anything …

Already at 4-5 days of age a child can be the testing of hearing — otoacoustic emissions. Inserted in the child's ear sensor sends sound signals of different frequencies. For 8 seconds, ear, if it hears these signals should reflexively generate very weak vibrations of sound that are detected by special microphone in the sensor. This reflex akin to rapping hammer on the knee: knocked — foot should be set in motion. So here: if the sound is accepted, must be the answer. If the answer is no, it is necessary to understand why.

— And the cure?

Yes. Even with severe hearing loss in the first class of the school can be adapted to the child's social environment. If, however, at an early stage does not identify hearing loss and do not start treatment, we run the risk of oral-aural leave the zone without the development of the child — to achieve the correct speech and sound-after five years would be impossible. Therefore, these patients usually do not just deaf and deaf-mutes. Just do not hear it and learn to say they did not work.

— It turns out that the earlier hearing loss detected, the better chance to recover it?

Or suspend its decline. But, unfortunately, many do not go to the doctor in time. About the specialized care they begin to wonder just when they no longer understand the voice of the caller. The human brain can be very long (10-15 years) to compensate for poor hearing, and then comes to the ridiculous: the patient asking, "What is your name?", He says "Dog". You begin to understand, it turns out that he, instead of "What is your name?" Heard the request to name the word "dog." Short words are perceived odnoslogovye the most difficult: the peak, teak, dark, laziness, a shadow — a fantasy played out unusually. To the extent that the patient may believe that talking to him in a foreign language.

— These people probably have serious problems with communication, spoiled character?

For them to have a normal life needs a hearing aid.

— But after hearing aid — it is so uncomfortable!

 

Were uncomfortable analog hearing aids. They enhance the sound at all ranges by an average of 30 decibels above the threshold of hearing. And well, if the patient's hearing loss was uniform — then he could help. And if the rumor was lost only on a part of the frequency, the machine will only help them, but in the perception of sounds with different frequencies arise discomfort. If a healthy person calmly picks up the sound to 120 decibels, that in people with sensorin
eural hearing loss below the pain threshold.

Now hearing aids are digital, multi-channel, each frequency can be increased independently of the other, so this problem is solved.

Moreover, if earlier prosthetic frequency range up to 4kHz, which placed the whole of human speech, that there are now devices with an extended range of up to 10kHz, for example, the Danish company Widex, which allow to compensate for the loss of hearing people who work professionally with sound. In the first place, of course, musicians. Of the special hearing aids can still remember the binaural aids Siemens — are installed on one machine at each ear, they set up and begin to work together.

Overall, come to the doctor— And he will pick you the most optimal model. And if you summarize, then, for any problems with hearing are always one way — to the otolaryngologist, audiologist.
