Why do hearing AIDS need professional fitting by audiologists and fitters?

"fitting" refers to choosing a hearing aid suitable for your hearing under the guidance of professional and technical personnel. Like glasses, hearing AIDS are another kind of physiological function AIDS that need to be fitted. First of all, people's hearing impairment varies widely. Take the deafness of the elderly as an example: different types of deafness, different degrees of hearing impairment, tinnitus, fear of loud voice, auditory discrimination, etc., lead to different hearing differences. And different hearing loss requires different hearing AIDS. In fact, even hearing impairment with the same nature and degree, everyone may feel differently. These differences may be related to living habits, working environment and subjective endurance. Different feelings, of course, the requirements for hearing AIDS are different. Secondly, there are many brands and models of hearing AIDS. For users, which one is more suitable for their actual needs is a very professional problem that users can't solve by themselves, and only professionals can choose for them. For example, how should patients with severe hearing loss who are allergic to strong sound choose hearing AIDS? Emphasize amplification, they will find the sound unbearable; Emphasis on strong sound compression leads to the signal sound is not true and clear enough. How to solve this contradiction is one of the important work contents of hearing aid fitters. Only when the user's hearing condition is fully consistent with the performance of the selected hearing aid can the best hearing aid effect be achieved. What if hearing AIDS are not professionally fitted or bought by professionals? Improper wearing of hearing AIDS is harmful and useless. Everyone's hearing condition is different, and the requirements for hearing compensation are also different. If you choose an inappropriate hearing aid, you may not be able to provide enough hearing compensation for the hearing loss. What is more noteworthy is that if the sound emitted by the hearing aid is too loud, it may damage the residual hearing, further aggravate the degree of hearing loss, and even damage the auditory nerve. In view of this, hearing AIDS can only be worn with confidence after being fitted by professionals, and only after being fitted correctly can the role of hearing AIDS really be brought into play. However, it is not only difficult to use hearing AIDS without experience, but also it is likely to damage the residual hearing of users, resulting in more deafness. Hearing AIDS belong to medical devices, so you must go to a qualified professional hearing service center for "fitting"! China's hearing aid industry is mixed, and the quality of hearing aid fitting is difficult to guarantee. Some people used to sell flowers and some clothes. They have not received formal training and education, so they can only say that they are selling hearing AIDS. I don't know that the hearing aid is not correctly matched, which not only makes users unable to hear clearly, but also may damage their hearing.
