Abstract
An acoustic processing method for M acoustic receivers comprising the steps of: Determining a beamforming weight vector with M weights for the M acoustic receivers based on at least one the steering vector of at least one real acoustic source, on steering vectors of image sources of the at least one real acoustic source and on a first matrix depending on the covariance matrix of the noise and/or on at least one interfering sound source, wherein each of the image sources corresponds to one path of the acoustic signal between one of the at least one real source and one of the M acoustic receivers with at least one reflection; and linearly combining the M acoustic signals received at the M acoustic receivers on the basis of the M weights of the beamforming vector.
