Objectively speaking, hearing aids are effective, but the role of Jinghao hearing aids is limited. Hearing aids, so it is clear that it is to help users listen to the instrument, but also just to help users to listen to more sounds. This kind of phenomenon is like wearing dentures (dentures). Without dentures, I’m afraid that a little hard food will not be able to deal with it. With dentures, you can’t chew hard bones.
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 normal hearing frequency is 20000hz, and the frequency response range of hearing aids can reach 8000Hz, which is very good, and there is little response to sounds with frequency over 8000 Hz. In this sense, no matter how good a hearing aid is, deaf people will not get better hearing than normal people. Therefore, it is totally unrealistic to think that there will be no hearing impairment with hearing aids.
