In HelloNation, Audiology Expert Dr. Elizabeth Welch of Franklin, TN Explains Why Hearing Aids Whistle and How to Fix It

FRANKLIN, Tenn., Oct. 30, 2026 /PRNewswire/ -- Why do hearing aids sometimes produce a high-pitched whistling sound? A HelloNation article breaks down the common causes of hearing aid feedback and distortion, and how adults in Franklin, TN, can resolve these issues with professional guidance and routine care.

The article explains that whistling, also called feedback, occurs when amplified sound leaks from the ear canal and loops back into the hearing aid microphone. This sound loop causes the device to emit a sharp whistle or other distorted noise. While this can be frustrating for users who rely on hearing aids for clear communication, the article emphasizes that feedback is a common and manageable issue—not a sign of device failure.

One of the leading causes of hearing aid feedback is a poor fit. According to the article, if the hearing aid does not sit securely in the ear canal, sound can escape and re-enter the device's microphone. This is more likely to occur if the shape of the ear canal has changed due to aging, weight fluctuations, or ear infections. Custom earmolds and regular professional adjustments help maintain a snug fit, which reduces the likelihood of whistling and improves sound clarity.

Earwax is another frequent cause of hearing aid distortion and feedback. The article highlights how wax buildup in the ear canal can interfere with sound transmission and create pressure that affects the device's performance. In some cases, this results in intermittent whistling or muffled sounds. The article advises adults to keep both their ears and devices clean and to consult audiologists for safe hygiene practices. Regular cleaning and professional inspection help prevent these common issues.

Programming and volume settings also play a role in hearing aid performance. The article points out that devices set too loudly or incorrectly programmed for a given environment may be more prone to feedback. While many modern hearing aids include adaptive feedback cancellation, the article notes that this feature works best when paired with a proper fit and routine hearing aid adjustments.

In Franklin, TN, adults experiencing hearing aid whistling can receive help at audiology centers and ENT clinics. The article explains that professionals will examine the device fit, look for earwax blockages, and check programming levels. Often, small adjustments to volume, frequency response, or mold design can eliminate feedback quickly. If problems persist, clinicians may recommend new components or more advanced features to address the issue long term.

Importantly, the HelloNation article stresses that hearing aid feedback does not mean the device is malfunctioning. Instead, it is a signal that something—such as fit, ear condition, or programming—needs to be addressed. Ignoring the issue may lead to reduced hearing quality and unnecessary frustration, while timely intervention keeps the hearing aid functioning at its best.

Maintenance also plays a major role in preventing feedback and distortion. The article encourages users to clean microphones and receivers regularly, check battery levels, monitor changes in ear anatomy, and store devices correctly. Professionals in Franklin can offer personalized care tips and help schedule regular checkups to ensure continued performance.

By understanding the causes of whistling and taking proactive steps, adults can ensure that hearing aids provide consistent sound and comfort. The article emphasizes that hearing aid adjustments are often simple and effective, allowing users to maintain clear communication and avoid the discomfort of distortion. For those in Franklin and nearby communities, expert support is readily available to keep devices working as intended.
