7 Tips to avoid Hearing aid or amplifier feedback

A whistling hearing aid or amplifier can be extremely annoying and upsetting, and happen with all hearing aids, however, don't despair, it happens and can be rectified.

Hearing aid or amplifier feedback occurs when sound that was supposed to go into your ear canal leaves your ear and jumps back into the hearing aid microphone. The sound then gets reamplified, and this causes your hearing aids to whistle.

Many hearing amplifiers come with feedback cancellation, but this doesn’t completely safeguard you from feedback. The Audiunt Hearing selection of premium hearing amplifiers all come standard with noise and feedback cancelation.

Here are the most common reasons for feedback and how to resolve them.

What causes my hearing aid or amplifier to whistle and what can I do about it?

  1. When you put your hearing device on in the morning and take them off in the evening, or when someone hugs you. This is perfectly normal because the hearing device is reacting to the sound bouncing back from your surroundings.
    To fix it: Hugs are good for your health, maybe limit excessive hugging.
  2. Hearing aid feedback could also be a sign that your hearing aids need to be cleaned.
    To fix it: Consult your user manual for cleaning, you should have received a cleaning brush with you hearing amplifier
  3. Too high volume: It can sometimes be tempting to turn up the volume on your hearing aids. But turning it up too loud can force the sound to re-enter your hearing aids, which causes whistling. 
    To fix it: Turn down your hearing device volume and avoid the point where the sound gets so loud that it creates feedback.
  4. Too much earwax: Your hearing aids help you hear because they deliver sounds to your ear canal. But if the ear canal is blocked by too much earwax, the sound can’t get through. So, it bounces back into your hearing aids – and they start to whistle.
    To fix it: Get your ears cleaned by a professional and, while you’re at it, make sure that there is no clogging in the hearting aids sound tubes.
  5. In general, if your hearing aids are not put properly in your ear, it gives the sound a chance to escape and re-enter the hearing aid microphone, so make sure they are sitting nice and tight in your ear.
    To fix it: You can always ask someone to check if it looks correct.
  6. Sound tube not secure: The sound tube that connects to the hearing device may not be firmly enough connected. Sometimes the tubing then starts to pull, so that it doesn’t have a tight fit anymore.
    To fix it: Ensure that the sound tube is tightly fit to the hearing device. Consult your user manual for additional fitting information.
  7. A poor fit of hearing aids with earmolds: Just like the rest of your body, your ears change over time. They may even change shape. If they do, the earmolds can become loose and do not seal properly. This means the sound gets away from your ear and back into your hearing amplifiers' microphones, and that causes feedback.
    To fix it: Get new earmolds fitted to your ear. Weight gain or weight loss can also affect your ears and the fit of the earmolds.

If you continue to experience problems with hearing aid feedback and can’t figure out the reason, ask your hearing care professional to help you.
