If the sound is not heard at all, is it also suitable for wearing a hearing aid?
In general, deafness can occur when a person is up to sixty years old. This is caused by degenerative aging of the auditory organs and is medically known as senile deafness. Many people have had a lot of time for hearing loss, and they don't care; when one day, they feel that their hearing is more serious than before, they only go to the hearing aid fitting center, and they have a pair of hearing aids for themselves.
First of all, "feeling" that you can't hear a single voice, you don't necessarily have no hearing at all. Secondly, whether or not you can wear a hearing aid must be determined by professional hearing tests. There are cases where you can hear a little sound and you can't wear a hearing aid. Therefore, you must test your hearing as early as possible to wear a hearing aid as soon as possible.
When do you need to wear a hearing aid:
In 1997, the World Health Organization (WHO) developed a hearing impairment classification: mild deafness is 26-40 decibels, which is often unclear when it is 3-5 meters. The moderate sputum is 41-60 decibels, and the distance is 1 meter. Unclear; severe deafness 61-80 decibels, need to speak loudly at the ear to hear; extremely severe deafness is 81 decibels or more, can hear very loud voice, can not tell the words. In the case of hearing loss, patients with hearing tests above 45 decibels and below 90 decibels may consider hearing aids when there is no effective treatment to improve hearing.
Generally, hearing aids with more than 40 dB need to be equipped with hearing aids. The earlier the matching, the better the effect.
In addition, we can consider whether we need to choose a hearing aid in two aspects:
First, if the hearing test results in a hearing loss and the extent to which a hearing aid is needed, then the hearing aid should be selected as soon as possible;
Second, hearing is a high-level, comprehensive, subjective feeling. Therefore, “needs” is also a signal. Once we feel comfortable listening in our lives, it also means that we need hearing aids. We should choose hearing aids as soon as possible.
If there is no sound for a long time to stimulate the auditory nerve, the hearing will gradually decline. If you can't hear the sound for a long time, the speech resolving ability will be weakened. In this way, after wearing the hearing aid, although you can hear the sound, you may not be able to hear what others are saying. So ideal.
