Hearing aid matching: audible but inaudible

I can hear you, but I don’t know what you’re talking about.

This is a common complaint of many people with poor hearing. I can hear you, but I can’t hear you clearly. There are many reasons for this. So what are the reasons?

Compared with the normal hearing group, patients with sensorineural or mixed deafness not only have the problem of perception of sound loudness, but also have the problem of poor speech resolution. In other words, when we talk at a normal volume, people with normal hearing have no trouble talking, while people with sensorineural deafness whose hearing threshold is 60 decibels may not be able to hear clearly, and some words with light pronunciation may not be able to hear at all. Hearing is the basic function of the auditory system, while listening clearly is a more advanced function. As long as there is a signal to the auditory center, we can hear it, but to hear clearly, we must also have the ability of auditory discrimination. What factors determine whether we can hear it clearly?

In the noisy environment, because the sound signal itself becomes unclear, normal hearing people can’t hear it clearly, and a similar situation will occur if the signal sound is too small. For example, the sound of the TV is too small, and our normal listeners can’t hear it clearly, but this is not the whole problem. Because we have enough room for hearing discrimination, we can understand without 100% listening clearly. Therefore, the less serious ear injury will not make the patients lose the ability of hearing discrimination completely.

At this time, we should consider the selection of hearing aids. In adults or the elderly, the loss of middle and high frequency is caused by the loss of multi-functional sensorineural and mixed neural hearing, the speech resolution is reduced, and the problem of hearing but not hearing clearly is reflected in daily life. In the long run, the brain will slowly lose a lot of speech memory, even after wearing hearing aids, it will take a long time to adapt to and restore part of the hearing, which is why we build The reason why hearing impaired people choose hearing aids as early as possible is discussed. Early detection and early intervention are necessary to protect and compensate the existing hearing.

The auditory center has more important acoustic signal analysis ability. If the auditory center is damaged, the auditory resolution will be worse. There is a kind of deafness caused by central disorder, which is called < a href = "HTTPS: / / Baike. Baidu. COM / item /% E4% B8% ad% E6% 9E% A2% E6% 80% A7% E8% 80% B3% E8% 81% 8B / 17636648?

Obviously, if you can’t hear it, you can’t hear it clearly; but even if you hear it, you still can’t hear it because of the decline of the analysis ability of the listening center.

For the patients with central deafness who wear hearing aids, the specific effect needs to be evaluated by audiology after trying to wear hearing aids. At the same time, combined with their own expectations, choose whether to choose hearing aids or not.
