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 17):
A hearing aid according to  claim 1  wherein the resulting adaptation parameter \u03b2 mix  is determined as belonging to points on a circle in the complex plane, or an approximation thereof.
