Those occasional squeaks or whistles that emanate from your hearing aids are known as feedback. They used to happen more frequently in earlier hearing aid models.
What exactly is feedback noise?
An acoustic feedback takes place when amplified sound from a receiver re-enters the hearing aid via microphone and gets amplified again. Overall, feedback sounds like a whistling noise. The sounds can fluctuate from a low hum to a high-pitched screech.
How can feedback noises be managed?
Most modern hearing aids have a feedback management feature that makes the whistling stop. There is usually a run through of this feature during your initial hearing aid fitting, or when there is a repair or modification.
Some cases may still cause feedback. These include:
Our hearing instrument specialists at Pure Sound can make changes to your hearing aids’ output and gain (amplification), which can prevent feedback. If you are experiencing feedback noises that you can no longer manage, please contact us to schedule an appointment.
Pure Sound will only be open by appointment and for essential visits at this time. Essential visits include all appointments that require repairs, re-fittings and new hearing aid fittings. If you are having any issues with your hearing aids, or need supplies for your hearing aids, please call us before stopping in at one of our office locations.
