Has your hearing aid ever made a "buzzing" sound like when the microphone is too close to the stereo?

Such howling is also known as hearing aid feedback. Even though many hearing aid products have feedback suppression function, it can still occur in many life scenarios, such as when you wear or take off the hearing aid in the morning and evening, or when someone hugs you. This is completely normal! This is because the sound that should have entered the ear canal escapes from the ear and is reflected back to the hearing aid, so that the sound is amplified again, which causes your hearing aid to start screaming.

However, hearing aid feedback may sometimes be a signal that your hearing aid has a problem or needs cleaning. Therefore,Enno hearingprovides you with some of the most common reasons for feedback and how to solve it.

Insufficient matching degree of ear mold / earplug

Like other parts of your body, the shape of your ears may change over time. If they change, the ear mold will become loose and cannot be sealed properly. This means that the sound may leave your ear and jump back into your hearing aid. This creates feedback. To solve this problem, you need to re customize the ear mold suitable for your ear. In addition, weight gain or loss will also affect the matching degree of your ear and ear mold.

All in all, please make sure that the hearing aid keeps a comfortable and tight fit in your ear, so as not to allow the sound to escape and re-enter the microphone of the hearing aid. You can always ask your family or seek aprofessional audiologist to check whether you wear it correctly.

Volume too high

Sometimes, someone likes to turn up the volume of the hearing aid. However, if the volume is turned too high, the sound will be forced to re-enter thehearing aid, resulting in howling. Therefore, turn down the volume of the hearing aid to avoid making the sound loud enough to generate feedback.

Broken sound guide pipe

For some hearing aids, the sound guide tube connected to the ear mold may harden and contract. Sometimes, the tube will begin to pull the ear mold, making it no longer suitable. This means that it is time to replace the sound guide pipe with a new one~

Your hearing aids can help you hear sound because they send sound into your ear canal. But if the ear canal is blocked by too much cerumen, the sound cannot pass through, and it will bounce back to your hearing aid - and they will start screaming.

If you have too much cerumen, it will not only clog your ear canal, cause problems with hearing aids, but also make your ears painful or damage your hearing. Therefore, ask a professional to clean your ears and ensure that the hearing aid receiver and vent are unblocked.
