Hearing aid feedback occurs when the sound that was supposed to go into your ear canal leaves your ear and jumps back into the hearing aid receiver.

Not completely. All hearing aids work based on signals receive and sounds amplify, no matter what brands they are and how expensive they sold. Usually, the digital chips inside Byroncare hearing aids were programmed with feedback suppression algorithms. But modern acoustic technology still unpromises to locate signals from the speakers successfully every time. So what we can do is to avoid the feedback phenomenon as much as possible by following the guidelines in user manuals.

Don't be panic, take off or turn off your hearing aids first. The most effective way to avoid feedback is to isolate the speaker and receiver. The following measures may help

A suitable dome can effectively isolate the speaker and receiver and provided a more “plugged” feel. #Occluding effect reduces chances of feedback but may cause the user's voice to sound unnatural. This happens because the body-transmitted own-voice sounds that would otherwise leave the ear canal are trapped inside it. Anchor attached to the earpiece help to enhance the stability of domes and the occluding effect

Properly adjust the position of the tube and dome to enhance the occluding effect. Sometimes, it just takes a little adju stment to make sure it’s positioned correctly

Lowing the hearing aid gains will also reduce the volume of leakage sounds from the ear canals. When the leakage sounds volume is less than a certain threshold, the feedback whistling will not occur.

Switching the environment mode into the noisy environment setting (two beeps) will decrease the gain intensity and reduce the volume of the sounds in all six gain levels. This measure effectively minimizes the occurrence of feedback and squealing.

Another common cause of hearing aid squealing or whistling is an excess of earwax. When too much earwax builds up in your ear canal, it can affect the fit of your hearing aid. It can also create a barrier that prevents sound from getting through. Then these sounds go back into the hearing aid, causing feedback.

If your hearing aids are fitting properly, clean, not too loud, and full of battery, there could be a bigger problem that requires professional diagnosis or repair. If the hearing aids start to have unsolvable feedback problems after normal usage, please contact our customer service.
