How to Reduce Feedback and Squealing from Hearing Aids and Hearing Amplifiers

If you or a loved one wears a hearing aid or amplifier, you may have experienced that annoying high-pitched squeal or whistle known as feedback. It’s not only frustrating—it can interfere with your ability to hear clearly and comfortably. In this guide, we’ll explore simple and effective ways to reduce feedback and squealing from hearing aids for seniors, hearing amplifiers, and other electronic hearing aids.

What Is Feedback and Why Does It Happen?

Feedback is the high-pitched sound that occurs when amplified sound from a hearing device leaks out and is picked up again by its microphone. This creates a sound loop that causes whistling or squealing.

It’s common in both electronic hearing aids and electronic hearing amplifiers, especially if the device isn’t fitting correctly, the volume is too high, or the ear canal is blocked with wax.

Common Causes of Hearing Aid and Amplifier Feedback

There are a number of reasons why your rechargeable hearing aids or rechargeable hearing amplifier might be squealing:

• Poor fit: If the earpiece isn’t snug, sound can escape and re-enter the microphone.

• Volume too high: Turning the volume up too far can increase the risk of feedback.

• Earwax build-up: Wax blocks sound, forcing it back out of the ear.

• Device not inserted correctly: Misplaced devices allow sound to leak out.

• Dirt or moisture: Blocked tubing or microphone ports can alter sound flow.

• Worn-out components: Tubing, domes or seals may degrade over time.

How to Prevent Feedback

1. Get a Proper Fit

Ensure your hearing aid or amplifier fits snugly. If it's too loose, it can cause sound to escape. Many hearing aids for seniors now come with custom or adjustable tips for a better seal.

2. Keep the Volume at a Comfortable Level

Avoid turning the volume up too high. If you're struggling to hear even at low to mid-level volumes, the device may need recalibrating rather than simply increasing amplification.

3. Clean Your Devices Regularly

Wax and debris can block microphones or tubing, causing sound distortion. Clean your rechargeable hearing aids or hearing amplifiers using a soft brush or the tools provided by the manufacturer.

4. Check Your Ears for Wax

A build-up of earwax is one of the most common causes of feedback. If you suspect wax is an issue, consider using ear drops or visiting a professional for removal.

5. Use Feedback Suppression Technology

Many modern electronic hearing aids and rechargeable hearing amplifiers are equipped with digital feedback cancellation. Make sure this feature is switched on, or ask your provider for assistance.

Troubleshooting Feedback at Home

If you’re experiencing feedback, try these steps before contacting a specialist:

• Reposition the device in your ear and ensure it’s seated properly.

• Test different volume levels to find the sweet spot.

• Try using the device in a quieter environment.

• Swap out domes or tubing if they appear worn.

• Fully charge your rechargeable hearing aid—low battery can affect performance.

When to Seek Professional Help

Some feedback issues require professional attention. Contact your hearing care provider if:

• The device squeals constantly, no matter what you try.

• The fit feels different or uncomfortable.

• The volume level isn’t helping improve sound clarity.

• It’s been over a year since your last check-up.

A professional can check for fit issues, perform a deep clean, or reprogramme your device if needed.

Choosing a Low-Feedback Hearing Aid or Amplifier

If feedback is a persistent issue, it might be time to upgrade. Look for:

• Rechargeable hearing aids with advanced digital noise suppression.

• Electronic hearing amplifiers that offer directional microphones and customisable settings.

• Models designed specifically as hearing aids for seniors, offering ease of use and comfort.

• Devices with closed-fit domes for improved sound isolation.

Brands and models vary, so it’s worth getting advice from a professional before buying.

Final Thoughts

Feedback and squealing are common—but avoidable—issues with hearing aids and amplifiers. Whether you're using electronic hearing aids or a rechargeable hearing amplifier, the key is proper fit, regular maintenance, and using the right device for your hearing needs.

If you follow the tips above and still notice problems, don’t hesitate to get expert advice. A small adjustment can make a big difference in both comfort and hearing quality.
