Hearing aids are life-changing devices that help millions of people reconnect with the world of sound. However, one common challenge many users face is hearing aid feedback—a high-pitched whistling or squealing noise that can be frustrating and disruptive. Understanding why feedback occurs and how to prevent it can help you get the most out of your hearing aids.
In this blog post, we’ll explore hearing aid feedback, what causes it, and practical steps to reduce or eliminate it.
What Is Hearing Aid Feedback?
Hearing aid feedback happens when the amplified sound from your hearing aid’s speaker loops back into the microphone, creating a high-pitched whistling noise. This feedback can be occasional or persistent, depending on the cause.
There are three main types of hearing aid feedback:
Acoustic Feedback – This occurs when sound escapes from the ear and re-enters the microphone, creating a whistling noise.
Mechanical Feedback – Caused by vibrations within the hearing aid components, leading to unintended sound loops.
Electronic Feedback – Results from internal issues within the hearing aid circuitry.
Common Causes of Hearing Aid Feedback
Poorly Fitted Hearing Aids
If your hearing aid does not fit snugly in your ear, sound can leak out and re-enter the microphone, causing feedback.
Earwax Buildup
Excess earwax can block sound from entering the ear canal properly, forcing it to escape and cause feedback.
Volume Set Too High
Turning up the volume too much can lead to sound leakage and create a feedback loop.
Physical Contact with Objects
Placing your hand near your ear, wearing hats, scarves, or even hugging someone can sometimes cause temporary feedback.
Damaged or Worn-Out Components
Cracks in the hearing aid tubing, worn-out earmolds, or internal component issues can contribute to feedback.
How to Prevent and Reduce Hearing Aid Feedback
1. Ensure a Proper Fit
If your hearing aid is loose or uncomfortable, visit your audiologist to adjust or replace the earmold. Custom-fitted hearing aids can help prevent sound leakage.
2. Keep Your Ears Clean
Regularly clean your ears to prevent earwax buildup. If you suspect excessive earwax, consult a doctor or audiologist for safe removal.
3. Adjust Volume Settings
Avoid setting your hearing aid volume too high. If you struggle to hear, speak with your audiologist about adjusting the programming rather than relying on volume increases.
4. Check for Damage
Inspect your hearing aids regularly for cracks, loose tubing, or worn-out earmolds. If you notice damage, consider replacing the affected parts.
5. Use Feedback Cancellation Features
Many modern hearing aids come with feedback suppression technology. If you experience frequent feedback, ask your audiologist about adjusting these settings.
6. Position Hearing Aids Correctly
Make sure your hearing aids are inserted correctly every time you wear them. Even small positioning mistakes can lead to sound leakage.
7. Be Mindful of Objects Near Your Ears
If you frequently wear hats, scarves, or glasses, check if they are interfering with your hearing aids. Try repositioning them to reduce feedback.
When to Seek Professional Help
If you’ve tried these solutions and are still experiencing persistent feedback, it may be time to consult an audiologist. They can:
Assess the fit of your hearing aids.
Adjust programming and feedback suppression settings.
Identify any underlying issues causing the problem.
Final Thoughts
Hearing aid feedback can be frustrating, but understanding its causes and taking preventive steps can help you enjoy clear, uninterrupted sound. A well-fitted, properly maintained hearing aid should provide seamless hearing without constant whistling.
If you’re struggling with feedback, don’t hesitate to reach out to a hearing professional. Small adjustments can make a big difference in your hearing experience!
