How to treat the function of hearing aids

Objectively speaking, hearing aids do work, but < a href = "http: / / www.sqhearing. COM / tlkp / 411. HTML" target = "_blank" > the role of hearing aids is limited. Hearing aid, as its name implies, is an instrument to help the user listen to the sound, and only to help the user listen to the sound. This kind of phenomenon is like wearing dentures (dentures). Without dentures, I’m afraid that a little hard food can’t cope with it; with dentures, you can’t chew hard bones.

How does the hearing aid, which is essentially an amplification device, work?

First of all, the hearing aid can amplify the sound signal to maximize the user’s perception of the sound. We all have such experience that it is not easy to hear too small a sound. Secondly, hearing aids can selectively amplify sounds of different frequencies according to the user’s hearing loss (for example, for patients with high-frequency hearing loss, high-frequency and multi amplification; for patients with low-frequency hearing loss, more amplification of low-frequency), so as to ensure that the user can hear and hear as much as possible. Thirdly, absolutely Most hearing aids focus on amplifying language frequency to ensure language communication; fourthly, after adding some special circuits, some hearing aids can amplify weak and small sounds, and also limit large sound output as required. Because of the above functions, hearing aids can benefit the vast majority of users.

However, hearing aids are not “omnipotent”, which can not be perfect, and can not solve all the problems of deaf patients. For example, the upper limit of high frequency of normal hearing is 20000hz, and the frequency response range of hearing aid can reach 8000Hz, which is very good, and there is little response to sound with frequency over 8000Hz. In this sense, no matter how good hearing aids are worn, deaf patients will not get better hearing than normal people. Therefore, it is totally unrealistic to think that wearing hearing aids will no longer cause hearing impairment.
