Abstract: The application relates to a hearing device adapted for being located at or in a first ear of a user, or to be fully or partially implanted in the head at a first ear of a user, the hearing device comprising a first input transducer for converting a first input sound signal from a sound field around the user at a first location, the first location being a location of the first input transducer, to a first electric input signal, the sound field comprising a mixture of a target sound from a target sound source and possible acoustic noise; a transceiver unit configured to receive a first quantized electric input signal via a communication link, the first quantized electric input signal being representative of the sound field around the user at a second location, the first quantized electric input signal comprising quantization noise due to a specific quantization scheme; a beamformer filtering unit adapted to receive said first electric input signal and said quantized electric input signal and to determine beamformer filtering weights, which, when applied to said first electric input signal and said quantized electric input signal, provide a beamformed signal, and a control unit adapted to control the beamformer filtering unit, wherein the control unit is configured to control the beamformer filtering unit taking account of said quantization noise. The invention may e.g. be used for the hearing aids and other portable electronic devices with limited power capacity.
