Many people who wear hearing aids often feel that the sound is loud, but they can’t hear what others are saying. This is because there is no “tailor-made” one that suits their hearing.Hearing aid, Not only did not achieve the effect of hearing aid, but also caused more serious damage to hearing.
According to audiology experts, the frequency of sound that human ears can hear is mainly between 250 Hz and 8000 Hz. The low frequency part mainly makes people feel the sound, while the high frequency part plays a decisive role in the understanding of language.When the elderly suffer from deafness, they have different degrees of loss in each frequency range, but most elderly people have serious high-frequency hearing loss, that is, they can’t hear people clearly. If there is no option to compensate for the high-frequency hearing loss ofHearing aid, It will not play the role of hearing aid.
Therefore, it is best to check the hearing of patients with back-of-the-ear hearing aids. In addition to checking the frequency of hearing loss, the degree of hearing loss and the resolution of language should also be checked.According to the specific situation of hearing loss, choose a hearing aid suitable for your hearing “degree”.And some elderly people suffering from acute deafness should go to the hospital for a comprehensive physical examination to determine whether it is necessary to wear hearing aids.If the ear canal discharges pus, you should stop wearing hearing aids.
In addition, according to audiology experts, there are mainly two types of analog hearing aids and digital hearing aids on the market.Digital hearing aids are more expensive than analog hearing aids, but their adjustable frequency range is wider and the hearing aid effect is better.
A number of studies have shown that hearing health is closely related to physical and mental health. Active listening and active participation in society make life more exciting and healthier.
