Hearing Aids Leading Brands

It doesn’t matter the style, brand name or cost of your hearing device you’re bound to hear your hearing aid squealing at some point after you have been using your hearing device. Sometimes a lot of people complain about the disturbing and irritating noises of the hearing aids. You may observe your hearing aids squealing or whistling.

The squealing or whistling of hearing aids

Whistling noise called “feedback” or “Acoustic feedback”  Every hearing user once in their life ask this question “Why does my Hearing Aid Whistle?” Common causes of feedback include excessive earwax buildup, cracked or broken tubing, poor fit, too much volume at certain frequencies or dislodged microphones. Whistling may be a general problem in hearing aids.

 The squealing or whistling might be the sign of different problems that are occurring in the functioning of hearing aid.

Even though the whistling might be a sign that a repair is desirable, it could be that an easy adjustment is required. If you hear whistling when you hold the hearing aid in your hand or place it up to your ear, the whistling as usual.

Occasionally the sound of hearing aid squealing is a perfectly usual occurrence. Other times it’s an indication that something else is wrong with your hearing aid. Hearing aids can squeal and produce various sounds like whistling, hissing, beeping and crackling.

It is always best to talk about your own individual requirements with an audiologist or hearing care professional (1800-121-4408) to make sure you are using the right hearing aid.

Why does your hearing aid squeal or whistle?

You can call whistling or squealing noise as Hearing aid Feedback. It is caused by sounds that depart your ear and find their way back into the microphone. From there, the sound is re-amplified that causes that annoying whistle.

Acoustic feedback occurs when the amplified sound coming away from the hearing device through the speaker (receiver), gets picked up by the hearing aid’s microphone again and again and creates an acoustic loop. This sound can sound like a whistle or squeal. 

Hearing machine feedback will happen after you put your hand up to your ear, once you’re hugging somebody, or when you’re inserting or removing your hearing aid. Or when something just like the back of your chair is within 3 or 4 inches of your ear. Numerous digital hearing aids approach with feedback cancellers to battle the annoying noise, however occasionally some feedback can still get through and there is very little that can be done to prevent it.

What are the reasons for these feedback noises?

  • Hearing aids that are not seated properly in the ear.
  • Loose-fitting hearing aids.
  • Blockage in the ear canal such as earwax.
  • Excessive jaw movement with chewing, smiling.

Vents

Vents can also cause hearing aid feedback problems. Do these holes be drilled into hearing aids that allow amplified sound to escape the ear canal? They help avoid the “occlusion effect,” an acoustic phenomenon that increases the volume perception of a person’s own voice due to sound trapped between the hearing aid and the eardrum.

How to stop your hearing aid from squealing or whistling?

To stop this feedback, don’t turn your hearing aid on until it’s in your ear. You can also turn the volume down low until the piece is located in your ear, then turn the volume back up to a standard level while you have it situated.

Almost all hearing devices will create feedback when something is placed next to the microphone. For example, when wearers cup their hands over their hearing devices while they are in the ears, they will usually whistle. To stop hearing aid feedback noise you should wear properly fitted hearing devices. Properly fitted hearing aids do not whistle during ordinary wear when there is nothing near the microphone.

Other feedback noises

Hissing sounds of Hearing Aid

The hearing aid makes a “scratchy” or hissing sound. It is possible for the hearing aid to make some unusual sounds that resemble scratching or hissing. Most often, those are caused by a collection of dust, lint or moisture.

Cracking sounds

When a hearing aid doesn’t fit tightly enough and sound “leaks” out of the ear or when the device is clogged with earwax. When a hearing aid produces this crackling sound, it usually means it needs service.

Beeping of hearing aid

Beeps can indicate that a battery is getting low, that the hearing aid program is changing (when you push the program button) or there are changes to the volume.
