Hearing device comprising a beamformer filtering unit

Abstract

A hearing aid comprises a) first and second microphones b) an adaptive beamformer filtering unit comprising, b1) a memory comprising a first and second sets of complex frequency dependent weighting parameters representing a first and second beam patterns, b3) an adaptive beamformer processing unit providing an adaptation parameter β(k) representing an adaptive beam pattern, b4) a memory comprising a fixed adaptation parameter β(k) representing a third, fixed beam pattern, b5) a mixing unit providing a resulting complex, frequency dependent adaptation parameter β(k) as a combination of said fixed and adaptively determined frequency dependent adaptation parameters β(k) and β(k), respectively, and b6) a resulting beamformer (Y) for providing a resulting beamformed signal Ybased 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(k).
