1. A method for noise reduction of a binaural microphone signal (x1, x2) with one target point source and M interfering point sources (n1, n2, . . . , nM) 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 (x1, x2) by a Wiener filter to obtain binaural output signals (ŝ

    L

    R) of the target point source, where the Wiener filter is calculated as;
