The feedback management system is a very important feature for providing good sound quality in a hearing instrument. With an effective feedback management system you will be able to provide the gain, clarity and comfort that is needed for a successful fitting.
As an amplified signal leaks out of the ear and is picked up by the hearing aid microphone, a feedback loop is generated and annoying feedback is heard. Beltone’s Improved Adaptive Active Feedback Cancellation (AFC) produces a
signal (grey wave) that is equal in frequency and amplitude but opposite in phase
to the feedback signal (blue line). The result is a cancellation of the whistling loop.
Beltone's Feedback Eraser with WhistleStop provides improved feedback path modeling and more added stable gain than any other feedback system on the market today.
