The importance of listening in daily communication needs no further explanation. But not everyone has no problem in listening. For people with hearing problems, hearing aids are an important guarantee for their normal communication. However, it should be noted that not all people wear hearing aids effectively, and the actual wearing effect of each person is different.
So which deaf patients can hearing aids help?

1. According to the nature of hearing loss
The ideal < a href = "http://www.sqhearing.com/tlkp/28.html" target = "blank" > hearing aid effect < / a > should be conductive hearing loss.
This kind of hearing loss mainly occurs in the outer or middle ear. Because of the blocked energy transmission, the patients with hearing impairment can not hear clearly.
Moreover, the dynamic range of hearing does not change, and the speech resolution is less affected, so the hearing effect of this kind of hearing-impaired patients is the best after amplifying the sound through hearing aids.
The second is mixed hearing loss.
This kind of hearing loss has both conductive hearing loss and sensorineural hearing loss.
Because sensorineural hearing loss will be revived, and the dynamic range of hearing will be narrowed, and speech resolution will be greatly affected, so the effect of hearing aids with mixed hearing loss is better than sensorineural hearing loss.
The worst use effect of hearing aids should belong to pure neuro hearing loss or central hearing loss.
Hearing loss patients of this nature cannot understand the meaning of sound, so they can hardly get the help of hearing aids.
2. According to the pathological cycle
The shorter the time of hearing loss, the better the effect of hearing aid. The effect of hearing aids is better in patients with post lingual deafness than in patients with pre lingual deafness.
The longer the time of hearing loss, the worse the perception and resolution of sound.
In general, the effect of hearing aids used by young patients with hearing impairment is better than that of old patients with hearing loss.
The ideal need of patients is to be able to listen like normal people after wearing hearing aids, but the reality is that this situation is very small. In terms of the compensation effect of current hearing aids, there is still a big gap compared with the human ear. And as time goes on, the compensation effect of hearing aids will be less and less.
