Abstract:
A hearing aid comprises a) first and second microphones b) an adaptive beamformer filtering unit comprising, b 1 ) a memory comprising a first and second sets of complex frequency dependent weighting parameters representing a first and second beam patterns, b 3 ) an adaptive beamformer processing unit providing an adaptation parameter β opt (k) representing an adaptive beam pattern, b 4 ) a memory comprising a fixed adaptation parameter β fix (k) representing a third, fixed beam pattern, b 5 ) a mixing unit providing a resulting complex, frequency dependent adaptation parameter β mix (k) as a combination of said fixed and adaptively determined frequency dependent adaptation parameters β fix (k) and β opt (k), respectively, and b 6 ) a resulting beamformer (Y) for providing a resulting beamformed signal Y BF  based on first and second microphone signals, said first and second sets of complex frequency dependent weighting parameters, and said resulting complex, frequency dependent adaptation parameter β mix (k).

Claim (Index 1):
A hearing aid adapted for being located in an operational position at or in or behind an ear or fully or partially implanted in the head of a user, the hearing aid comprising\n first and second microphones for converting an input sound to first IN 1  and second IN 2  electric input signals, respectively, an adaptive beamformer filter for providing a resulting beamformed signal Y BF , based on said first and second electric input signals, the adaptive beamformer filter comprising, a memory comprising\n a first set of complex frequency dependent weighting parameters W o1 (k), W o2 (k) representing a first beam pattern (O), where k is a frequency index, k=1, 2, . . . , K, and \n a second set of complex frequency dependent weighting parameters W c1 (k), W c2 (k) representing a second beam pattern (C), \n an adaptive beamformer processor for providing an adaptively determined adaptation parameter \u03b2 opt (k) representing an adaptive beam pattern, said memory further comprising a fixed frequency dependent adaptation parameter \u03b2 fix (k) representing a third, fixed beam pattern (OO), a mixer configured to provide a resulting complex, frequency dependent adaptation parameter \u03b2 mix (k) as a combination of said fixed frequency dependent adaptation parameter \u03b2 fix (k) and said adaptively determined frequency dependent adaptation parameter \u03b2 opt (k), a resulting beamformer (Y) for providing said resulting beamformed signal Y BF  based on said first and second electric input signals IN 1  and IN 2 , said first and second sets of complex frequency dependent weighting parameters W o1 (k), W o2 (k) and W c1 (k), W c2 (k), and said resulting complex, frequency dependent adaptation parameter \u03b2 mix (k).
