Abstract (en)

[origin: EP1469702A2] Feedback suppression is performed at a hearing device with a controllable beamformer (12) and a feedback compensator path (18) in that the adaptation rate of acoustical/electrical conversion including beamforming is controlled in dependency of the gain along the feedback compensating signal path (18).
