Hearing aid troubleshooting

Hearing aid troubleshooting

In daily life, if the hearing aid fails, it can be eliminated in some simple ways. Note that if you can't solve the problem in a simple way, please don't disassemble the hearing aid. Please go to the fittings to solve the problem.

First, the sound is distorted or noise is present

1) Check if the volume is too loud;

2) Change to a new battery and check if the battery is exhausted;

3) For the behind-the-ear hearing aid, check whether the sound hole of the ear mold is blocked, whether the sound tube is twisted or twisted; whether the sound tube is damp; whether the ear hook is blocked. Whether the sound hole of the custom machine is blocked by ear wax; for the box type hearing aid, it is also checked whether the earphone wire type is correct, the earphone wire connector is in good contact, and the earphone is broken.

Second, the situation of howling

When you wear a hat and your palm close to the hearing aid, it is normal for the hearing aid to appear a short whistle.

If there is frequent whistling, it may be caused by improper wearing of the ear mold or hearing aid, etc., and the wearing position can be appropriately adjusted.

Third, the sound is always intermittent

1) Change to a new brand of batteries to see if the battery is not suitable.

2) Check if the surface of the battery is clean. You can wipe the surface of the battery with cotton 蘸 pure alcohol.

3) Check if the battery compartment is clean. If there is any foreign matter, use a cotton swab with pure alcohol to wipe it gently. If you find any foreign matter on the pole piece that is difficult to remove, please do not solve it yourself.

Whether the sound hole of the custom machine is blocked by ear wax; for the box type hearing aid, it is also checked whether the earphone wire type is correct, the earphone wire connector is in good contact, and the earphone is broken.
