Feedback Manager
- Feedback (whistling) is caused by amplified
sound being fed back into the hearing aid
receiver, being amplified again, and being
fed back in again. This phenomenon normally
happens at the resonant frequency of the
auditory canal (about 3 KHz.) The feedback
manager dampens this frequency (and frequencies
adjacent to it) to prevent feedback occurring.
