Users of hearing aids must understand the working principle of hearing aids and the basic functions of various components. Of course, different types of hearing aids have their own differences, but the main components are similar.

Microphone: collect sound and convert it to electrical signal

Amplifiers: amplifying electrical signals

Battery: power amplifier

Volume potentiometer: adjust the volume of the hearing aid

Headphones: converting electrical signals from amplifiers to acoustic signals

Hearing impaired patients often report that the hearing aid has always been good. How can there be no sound at once? In this case, there are only several reasons:

1. The acoustic hole of the hearing aid is blocked by cerumen. Just clean the acoustic hole. If you can’t clean it, you can go to the fitting center to clean it.

2. The microphone is blocked by dirt. Its processing method is basically the same as the first one.

3. The battery is dead. Replace the battery.

4. The hearing aid is damp. Dry the hearing aid. It is recommended to go to the fitting center.

5. Turn the volume adjustment knob, that is, turn off the volume switch and turn it on.

6. For the ear back hearing aid, you can also see if there is any water drop in its acoustic pipe. If there is, it is blocked by the water drop. Take off the acoustic pipe, dry and clean it.

If none of the above situations are true, it is recommended to send the hearing aid to the manufacturer for maintenance.
