Hearing aid is an auxiliary device that people with hearing loss can use. Today’s hearing aid has become smaller and smaller, so it can be put into our ear canal. What’s the role of a small hearing aid?
The role of hearing aids is to improve our hearing ability. The principle of the initial design of hearing aids is to accept the external sound, then amplify it and then introduce it into our ears. Hearing loss patients can improve their hearing ability by wearing hearing aids.
Many people can hear the cell phone ring, the bird call outside, the door ring and so on after wearing the hearing aid. After all, it’s inconvenient for our life if we can’t hear the sound because of the bad ears. At the same time, there will be some security risks.
Secondly, wearing hearing aids can improve speech recognition ability. Many patients’ hearing loss is accumulated for a long time, so their speech recognition ability will be reduced. Therefore, they will not be able to hear clearly and understand. Wearing hearing aids for a long time can improve this and improve speech recognition.
Then there’s a point: hearing aids can’t treat hearing loss. It’s just an auxiliary device. Many people think that hearing aids can treat deafness. This is the wrong view, just like glasses can treat myopia.
