Hearing device with motion sensor used to detect feedback path instability

An ear-wearable device, comprising:

• an input sensor that provides an audio input signal, the audio input signal being digitized via circuitry of the ear-wearable device;
• an adaptive feedback canceller comprising an adaptive filter producing an output that is inserted into the digitized audio input signal to cancel feedback;
• a motion detector providing a motion signal indicative of motion of the ear-wearable device;
• and
• a processor operable to determine a change in a feedback path based on the motion signal, the processor causing the adaptive filter to have faster adaption in response to the change in the feedback path is above a first threshold, the processor causing the adaptive filter to have slower adaption in response to the change in the feedback path being below a second threshold.
