Some of the most common problems that can occur during the lifetime of a hearing aid are connected to the electronics, external parts such as domes and tubing, batteries, dirt, earwax, moisture or extreme temperatures. Depending on the exact cause, the wearer may be able to solve the issue on their own or alternatively, turn to a specialist for advice or repair.
No sound from the Hearing Aid
This is one of the most common reported problems connected to the performance of hearing aids. There are a few ways to find the source of the issue and various solutions to it. First, it is best to check if the hearing aid is turned on and that the volume is increased. If it is, then proceed to see if the T-switch is in the right position. Dead or wrongly inserted batteries can also result in the aid not functioning, so you need to make sure that the batteries are fresh and making a proper contact. Check for any traces of corrosion in the battery compartment and ensure that the tubing or ear mould is not clogged with dirt or earwax.
Hearing Aid only has a Weak Sound
Another issue that you may run into is that the hearing aid produces sounds but not as strong as before. Possible reasons for that can be a crack or deformation in the dome and tubing. If that is the case, you need to replace them with new ones and see if there is any improvement. Old batteries can also lead to fainter sound as well as moisture and dirt. Be sure to clean you hearing aid parts regularly from debris and earwax as even small accumulations may cause problems with the strength of the signal you receive.
Hearing Aid Feedback Noise
Feedback is an unpleasant whistling noise due to a sound loop produced by the hearing aid. First, you need to check if the volume is not too high and if any objects such as hats or scarfs are not covering the device. Another source could be a loose fit of the ear mould or dome and you will need to insert it again and make sure it is properly positioned. Also, make sure that there is no blockage caused by earwax. If the feedback you hear is consistent, there could be a problem with the wiring and you will need to see a specialist to replace or repair it.
When the sound is distorted or the quality of the performance varies, it is best to check the batteries and see if they are inserted the right way and that there is no moisture or dirt in the battery compartment.
