Hearing aid feedback is sound that escapes, reaches the device’s microphone, and is amplified again. It can sound like a whistle or squeal. A persistent whistle deserves a fit and device check; it is not a reason to keep turning the volume down until speech becomes difficult to hear.
The most useful first step is to record when it happens. A whistle only while putting a hearing aid on is a different observation from a whistle that continues after the device is in place. Neither pattern, by itself, identifies the cause.
First, separate a device noise from a hearing symptom
If you notice a sudden change in your hearing, seek urgent medical assessment. Do not assume the hearing aid or earwax is responsible. NIDCD advises treating sudden hearing loss as a medical emergency.
If ringing continues when the hearing aid is removed, describe that separately to a clinician. Ear pain or bleeding also needs medical assessment. This guide is about observing a device problem, not diagnosing tinnitus, an ear blockage, or a medical condition.
What can contribute to feedback?
Starkey’s feedback explanation identifies fit and seating problems, an inadequate earpiece seal, and earwax as possible contributors. Feedback management and programming can also be part of professional assessment. The appropriate response depends on what is actually causing the problem.
That is why a bigger dome or a new hearing aid is not an automatic solution. The person checking the device needs to consider its fit, condition, settings, and your ear. Avoid changing several things at once before the visit; that can make it harder to explain the original problem.
Use a short whistle record
| When it happens | What to note |
|---|---|
| While inserting or removing the device | Whether it stops after normal placement |
| When a phone, hat, or headset is close | Which item and whether it touches the hearing aid |
| When speaking, chewing, or turning | Which movement and which ear |
| After a dome change or repair | Date, replacement packaging, and what changed |
| During ordinary conversation | Whether it is continuous and whether others hear it |
You do not need a long diary. One or two specific examples can be more useful than a week of “it sounds bad.” If a companion hears the noise when you do not, include their observation without treating it as a diagnosis.
What is reasonable to check at home?
Use the placement method you were taught. Check externally for a visibly damaged or missing earpiece, and follow only the care instructions supplied for your model. If something appears loose, torn, or out of place, stop using that device until you have appropriate guidance.
Do not force the hearing aid farther into the ear to silence it. Do not plug a vent, glue a dome, swap the left and right devices, or try to remove earwax with a tool. A change that stops a noise temporarily can still be inappropriate for the fitting.
If the noise occurs with glasses, a hat, or headphones, bring that item to the visit. It is easier to evaluate a repeatable interaction than to recreate it from a general description. Do not deliberately repeat a painful or uncomfortably loud situation.
What to ask during the check
Ask the team to explain what they found and what the next step is. If an earpiece is changed, ask whether the programming or feedback settings need to be checked as part of that change. If service is needed, ask what can be assessed locally and what requires additional work.
Useful questions include: “Is the fit still appropriate?” “Is there visible damage?” “Does the noise occur with my usual phone or glasses?” and “What should I watch for after this adjustment?” Keep the answer tied to your device rather than a universal rule about a brand.
Feedback does not automatically mean replacement
A hearing aid can need attention without needing to be replaced. At the same time, an online checklist cannot establish that the problem is minor. Avoid both extremes: assuming the device has failed, or assuming persistent whistling is something you must tolerate.
The decision should follow an assessment and a clear explanation of options. If repair or replacement is discussed, ask about expected benefit, limitations, support, and cost before deciding. There is no need to make that decision based on the whistle alone.
Our device service and troubleshooting support is for prescription hearing aids. The Hearing Guy does not service OTC hearing devices. For OTC device support, contact the manufacturer or seller.
Bring the problem into the room
The Hearing Guy serves Asheville and Hendersonville with fitting, programming, and hearing aid repair services. Our team includes Dr. Brent Steele, MD, BC-HIS.
Request a visit and bring your devices, the items associated with the noise, and a short note about when it occurs. A useful outcome is understanding the cause and what to do next, rather than simply finding a way to mask the sound.
