Abstract:
1. A method for noise reduction of a binaural microphone signal (x 1 , x 2 ) with one target point source and M interfering point sources (n 1 , n 2 , . . . , n M ) as input sources to a left and a right microphone of a binaural microphone system, the method comprising the following step: filtering a left and a right microphone signal (x where H W is the Wiener filter, Φ (x +x )(x +x ) is an auto power spectral density of a sum of all of the M interfering point sources components (x 1,n , x 2,n ) contained in the left and right microphone signals (x 1 , x 2 ) and Φ (x +x )(x +x ) is an auto power spectral density of a sum of left and right microphone signals (x 1 , x 2 ).
