You seem clueless about what is happening, and it is giving you a lot of stress as you might feel that you’ve been missing a lot whenever you are unable to hear? Whistling may happen in every hearing device at some point of wearing it, no matter what type of device you have.

How inconvenient it is to visit a Hearing Center every time you are having this irritating sounds? You can skip this Hearing Center visit by understanding how whistling or feedback happens, and by learning how to fix it by yourself.

Understanding how hearing devices work.

Hearing devices from Complete in the Canal to BTE’s have a microphone where a sound will be received and will be processed. It will then be converted from a sound to an electric signal. Because of its function, the microphone is always being placed in the outermost part of a hearing device. Once the sounds have been processed and converted, it will then be sent to the speaker/amplifier for this sounds to be louder.

Why does Whistling happen?

Since we already have a basic knowledge about how a hearing device works, we can now tackle more about hearing devices’ feedback or whistling problems.

A well-fitting hearing device that is working properly, free of ear wax, dirt and moisture, has a working battery, and was placed correctly into the ear canals shouldn’t whistle.

Whistling or feedback usually happens when a sound that was picked up and processed by the microphone will be forwarded to the amplifier, but instead of it being released directly to the wearer’s ear, these sounds were continuously being picked up by the microphone and being re-amplified all over again, continuously.

Wihear has compiled the common reason of whistling and how to avoid it so you can enjoy your hearing device with less complications. 

  1. Placed hearing device correctly.

Sometimes, you can experience feedback by not placing the hearing device correctly into our ears. It can be resolved by only removing the device from your ear and insert it again, correctly. It means that feedback only happens because the device was not properly placed in the ear and sounds being processed by the hearing device leaked out.

  1. Check for Ear Wax.

An ear wax blockage can also cause feedback as it will not allow the sounds to travel into the ear. The sounds being processed by the hearing device have nowhere to go because of the ear wax blockage, thus resulting these sounds to bounce back and it causes feedbacks or whistling. This can be resolved if earwax will be removed, from the user’s ears and from the device itself.

  1. Volume too high.

Wearing the device in a maximum volume or too loud volume may cause feedback or whistling as the volume may be too strong for the user. It can be resolved by adjusting the volume down.

  1. Check the Fit.

A not so fitted earplugs may cause whistling or feedback as sounds being picked up by the microphone and being released by the amplifier escapes user’s ear canals. It is being resolved by making sure that the user is not using too tight or too loose earplugs. Not changing earplugs regularly may also cause it to be a poor fit. Make sure to change earplugs regularly or once its color turned to yellowish.

If you have lost much weight lately, this can affect the fitting of the earplugs as well and you may need to try other sizes of earplugs already.

  1. Some movement and covers.

Covering your ears by a scarf or cap can cause changes in sounds pathways, thus making the hearing device whistles. The same effect will happen if you cover your ears, hug someone, or if you have a solid surface behind your back within 3 feet away.  The feedback that is being caused by the above reasons can diminish after removing any cover, letting go of a hug or moving to another place.

 

If all of the above tips are still not making the feedback stop, maybe it is time for you to change your hearing device’s battery. There’s a chance that the sounds you are hearing are just a low battery indicator and not a feedback itself.
