What is recruitment? Causes the elderly to dislike loud voices

Sponsored:

Do you talk loudly to your grandma or grandpa?

But did you know that this is actually counterproductive?

It has to do with recruitment.
Recruitment is a symptom of auditory hypersensitivity, which can also occur with age-related hearing loss, sudden hearing loss, and Meniere's disease.

Read this and you too will understand why you should never speak loudly to the elderly!

What is recruitment?

Complementary phenomenon is a symptom of auditory hypersensitivity that occurs in sensorineural hearing loss.
In addition to hearing loss, there are other symptoms of hearing loss that can cause sounds to sound louder.
This is auditory hypersensitivity.

It is especially common in age-related hearing loss, sudden hearing loss, and noise-induced hearing loss.

It is a supplementary phenomenon in which a person who does not have a hearing loss cannot hear a volume that is normally audible, but after a certain volume, it sounds equally or even louder.

The problem is that the loudness depends on the height of the sound. It is especially sensitive to high-pitched sounds and sudden noises.

In addition to sounding noisy, your ability to hear remains diminished, so you can't understand why the other person is saying what they are saying.

This leads to a situation where you just hear loud noises.

Causes of Recruitment

Reclusion is thought to be caused by cell damage in the inner ear.
However, it is only a thought and the cause has not been clearly elucidated.

Treatment of Recruitment

There is currently no cure for recruitment.
It is said that once your hearing recovers, the ringing may go away, but unfortunately, once your hearing is gone in the first place, it cannot be restored.

Your hearing will improve!

I've seen books in bookstores that say, "You can improve your hearing!

In the case of sudden hearing loss, it is possible to regain some hearing if treated within 48 hours, so if you suddenly lose your hearing, see a doctor immediately!

Sudden hearing loss can be treated within 48 hours and some hearing may return.

How to test for recruitment

Reclusion can be confirmed by tests called ABLB test, SISI test, and self-administered audiometry.

The ABLB test is performed when there is a difference in hearing between the left and right sides of the ear. If there are symptoms of recruitment, the difference between the left and right sides will disappear as the sound is increased.

The SISI test is performed by playing a sound that is about 20 dB louder than what you can hear, and then increasing the sound by 1 dB for a short time.
Normally, people cannot detect a 1 dB increase, but if you have symptoms of reclusion, the change will be greater and you will be able to detect it.

The test for recruitment basically relies on the person's senses.

Points to keep in mind when talking to the elderly

I'm sure you'll be able to understand me if you talk to me in a loud voice. I've seen this sometimes.

This is completely counterproductive for elderly people who are deaf and have the phenomenon of replenishment.

Just as there is a focus that makes it easier to see when your eyes are bad, there is a volume that makes it easier to hear when your ears are bad.

In fact, it is quite difficult to find the point at which it is easy to hear, but in the case of supplementary phenomenon, the volume is 20 dB higher than the volume at the edge of hearing.

In the case of supplementary phenomenon, the volume should be 20dB higher than the volume at the edge of hearing.
