Adaptive Feedback Cancellation

Detects sudden feedback (whistling or squeal) in a hearing device then removes it by applying a cancelling signal. If the cause of the feedback changes, the cancelling signal will automatically adapt. Adaptive Feedback Cancellers are designed to manage transitory feedback (e.g. feedback that happens when you place a hand or telephone next to your ear). This doesn’t resolve on-going feedback, which might be due to a poorly fitted earmold or hearing device.
