Why Would Whistling Noise Happen? Poor Fit: If the hearing aid or the eartip is not fitting properly in the ear canal, sound can leak out and find its way back into the microphone, causing feedback. Earwax Buildup: Excess earwax can block the ear canal, creating a gap between the hearing aid and the ear canal wall, which can lead to whistling. Microphone and Receiver Placement: If the microphone and receiver (speaker) are placed too close to each other, the sound from the receiver can be picked up by the microphone, creating a feedback loop. Volume Settings: Setting the volume too high can increase the likelihood of sound leaking out of the ear and being picked up by the microphone, causing whistling.

Solutions to Prevent Whistling Noise: Ensure Proper Fit: Make sure the hearing aid and eartips are properly fitted to your ear canal. Custom-fitted eartips can help achieve a better seal. Clean Your Ears and Hearing Aid: Regularly clean your ears and hearing aids to prevent earwax buildup and maintain proper function. Adjust Volume Settings: Avoid setting the volume too high. If you need a higher volume, consult with an audiologist to adjust the hearing aid settings properly. Regular Maintenance: Regularly check and maintain your hearing aids. Replace any worn or damaged parts, such as eartips or tubing.
