Is there a hearing aid with deafness??Really useful??I believe that everyone should have a general understanding. Our treatment of hearing is not a step. This is a long process. We should also use hearing aids scientifically. Remember how to use them.

Generally, the inaudible is caused by high frequency damage. The high frequency is the main area of ​​speech understanding. The sound waves enter the ear canal and pass to the tympanic membrane. The tympanic membrane generates vibration. The vibration is transmitted to the middle ear to make the small bone also vibrate and amplify the sound. The vibration of the sound is transmitted to the inner ear into the cochlea. The hair cells transform the vibration into electrical impulses. The electrical impulses are transmitted along the auditory nerve to the brain, where the brain analyzes and understands our speech signals. Therefore, most of the inaudible is the nerve damage, the patient’s cochlear lesions, can not transmit the words heard to the brain, can not get the brain’s response, so I feel that I did not hear clearly. For such hearing loss, it is very important to choose the hearing aid. If you want to choose a number of sound channels, you must have a hearing aid with frequency conversion function to make you listen well.
