If you wear hearing aids, you might have encountered an unexpected whistling sound from time to time. This noise, known as “feedback,” can occur for several reasons.
Feedback can happen while inserting or removing your hearing aids or, less conveniently, during times when you’re concentrating. While occasional feedback is usually harmless, frequent whistling could indicate a need for adjustments, especially when you first begin wearing hearing aids or change models.
Hearing Aid Style Can Impact Feedback
The likelihood of hearing aid feedback can be influenced by the type of device you wear. Some designs, like Behind-The-Ear (BTE) models, are generally more prone to feedback than smaller styles, such as In-The-Ear-Canal (ITEC) devices. If you notice a regular whistling sound, a hearing specialist may need to modify your device settings to minimize this effect.
Lowering Volume May Help Reduce Feedback
In many cases, feedback can be addressed by simply lowering the volume on your hearing aids. When the volume is too high, sound may loop back into the device, creating the whistling effect. However, if you find it difficult to hear at a lower volume, it might be time to consult your audiologist, as they can recalibrate your settings to suit your needs.
Proper Fit is Important
Our ears change over time, whether due to natural aging or weight changes, which can alter the fit of your hearing aids. If the earmold no longer creates a snug seal, feedback can result. Getting refitted with new earmolds that conform closely to your ear’s shape should alleviate the problem.
Check for Issues with Microphone or Tubing
Persistent feedback might signal an issue with a particular part of your hearing aids. For example, the microphone may be slightly misaligned, or the tubing may have hardened or shrunk over time. In such cases, professional assistance is needed to examine and correct the device.
Keep Hearing Aids Clean to Prevent Earwax Buildup
Excess earwax can interfere with sound flow, redirecting it back into the hearing aid and causing feedback. Regular cleaning of your hearing aids can prevent earwax buildup, which not only reduces feedback but also promotes better device performance and comfort.
To keep your devices functioning optimally, establish a consistent cleaning routine, store them properly and schedule periodic checkups with a hearing aid specialist.
