Hearing loss is almost the same. Why is the effect of wearing a hearing aid different?

      Since the hearing loss is not large, effective listening can be achieved in a quiet state, because the general speech sound in a quiet state can reach about 60-70dB, which is greater than the degree of hearing loss, so you can get enough without hearing aids. Speech intelligibility, but hearing difficulties in crowded and noisy environments.Under normal speech conditions, the help of hearing aids is not obvious. After all, people’s communication sounds can be above the listening range in a general living environment.

      Therefore, hearing aids are more helpful to users who have relatively heavy hearing loss and who have higher listening requirements, and are relatively less helpful to users who have light hearing loss.

      First of all, we should understand the two different concepts of hearing and comprehension. Hearing can be achieved as long as the power of the hearing aid is properly amplified and effectively amplified, but comprehension is a correct analysis and judgment made by the brain on sound information.Therefore, the brain response and function of different elderly hearing aid users are different, and the same hearing aid will produce different hearing aid effects.

      Due to the serious high-frequency hearing loss, and people’s speech intelligibility is closely related to high-frequency hearing, current research has found that there is still a problem of cochlear high-frequency dead zone. Therefore, although hearing aids can improve hearing, they still cannot solve the problem of clear hearing. Understand and understand the purpose of language.The use of frequency shift technology to achieve audibility expansion is also a new attempt. It can be seen that the same degree of deafness and different deafness properties are also important factors that affect the effect of hearing aids.
