Abstract: An illustrative wearable hearing device or hearing aid includes: a speaker that converts a reproduced signal into reproduced audio; a microphone that converts ambient audio into a receive signal, the ambient audio potentially including a feedback component; a feedback filter that filters the reproduced signal to obtain an estimated feedback component; a combiner that derives the reproduced signal from the receive signal at least in part by subtracting the estimated feedback component; and a controller that, subject to an adaptation rate, adjusts coefficients of the feedback filter to at least partially cancel the feedback component, the controller varying the adaption rate based at least in part on one or more proximity sensor signals.
