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 5):
A hearing aid according to  claim 1  wherein said adaptive beamformer processor for providing said adaptively determined adaptation parameter \u03b2 opt (k) representing said adaptive beam pattern is configured to attenuate unwanted noise under the constraint that sound from a target direction is essentially unaltered.
