Abstract
A hearing aid system with improved adaptive feedback suppression based on an improved feedback path change measure and a method of operating such a hearing aid system.
Claims10
A method of operating a hearing aid system with adaptive feedback cancellation comprising the steps of:
- a) determining at least one feedback path change measure based on at least one characteristic of an adaptive feedback cancellation filter;
- b) carrying out, based on said at least one feedback path change measure, at least one of:
- controlling adaptation speed of said adaptive feedback cancellation filter and applying decorrelation.
A hearing aid system comprising a feedback path change measure unit and a change measure controller, wherein said feedback path change measure unit is adapted to determine a feedback path change measure based on at least one characteristic of an adaptive feedback cancellation filter and wherein said change measure controller is adapted to at least one of controlling adaptation speed of an adaptive feedback cancellation filter and applying decorrelation.
