If you wear hearing aids, you may have experienced an annoying whistling sound from time to time. This high-pitched noise can be frustrating, making you wonder why it happens and how to stop it. Fortunately, the whistling sound—also called feedback—is a common occurrence that can often be resolved with a few adjustments. In this blog, Southern ENT Specialists will explore the causes of hearing aid whistling and what you can do to prevent it.
What Causes Hearing Aids to Whistle?
The primary reason for hearing aid whistling is feedback. This occurs when amplified sound from your hearing aid escapes your ear and re-enters the device’s microphone. The hearing aid amplifies this sound again, creating a feedback loop, which leads to the whistling noise you hear. Several factors can cause this feedback loop:
Improper Fit
Hearing aids are designed to fit snugly in your ear. If they don’t fit correctly, the sound can leak out, causing feedback. Whether the device is too loose or has shifted slightly due to movement, an improper fit can allow sound to escape, creating that unmistakable whistling sound.
Earwax Build-Up
Excess earwax can block the ear canal, preventing sound from entering your ear correctly. When this happens, sound can be reflected back into the hearing aid’s microphone, leading to feedback. Regular ear cleaning is crucial for maintaining your hearing aids and preventing this issue.
Volume Too High
Sometimes, the whistling occurs because the volume on your hearing aid is too high. When the sound is amplified too much, it increases the likelihood that it will escape the ear and be picked up again by the microphone.
Deteriorating Components
Over time, the parts of your hearing aids—such as tubing, microphones, or earmolds—can wear down. Worn or damaged parts can create gaps that allow sound to leak, causing feedback. Regular maintenance is essential to ensure your hearing aids are working correctly.
Tips to Prevent Hearing Aid Whistling
Hearing aid whistling doesn’t have to be a regular part of your life. Here are our top tips to minimize or even eliminate feedback issues:
- Ensure a Proper Fit: Work with your audiologist to ensure your hearing aids fit properly in your ear. Custom molds may be necessary to create a snug fit that prevents sound from escaping. Additionally, regularly check the fit of your hearing aids, as changes in weight or ear shape can affect how well they stay in place.
- Clean Your Ears and Hearing Aids Regularly: Keep your ears clean and free of excess earwax, as this is a leading cause of feedback. Make sure to clean your hearing aids regularly as well, paying attention to any blockages in the tubing or earmolds that could lead to sound leakage.
- Adjust the Volume: If your hearing aids are set to a high volume, try turning them down to see if that reduces the whistling. Your audiologist can help adjust your settings to provide the right balance between amplification and comfort.
- Schedule Regular Maintenance: Like any piece of technology, hearing aids require routine maintenance. Schedule regular appointments with your audiologist to check for worn parts and ensure your devices are working at their best.
Modern Solutions for Hearing Aid Whistling
Today’s hearing aids are equipped with advanced technology that significantly reduces feedback. Digital hearing aids have feedback suppression features that actively identify and cancel out whistling noises. These features make it easier to enjoy clear, uninterrupted sound without the nuisance of feedback.
If you’re experiencing frequent whistling despite following the above tips, it may be time to consider upgrading to newer technology. An audiologist at Southern ENT Specialists can help you explore your options and find the best hearing aids for your needs.
