Abstract:
A hearing device for a binaural hearing system comprising the hearing device and a contralateral hearing device is disclosed. The hearing device comprises a transceiver module; microphones for provision of first and second microphone input signal; a first beamforming module for provision of a first beamform signal based on the first microphone input signal and the second microphone input signal; a filter bank for filtering the first beamform signal into a plurality of first sub-band beamform signals including a first bandpass beamform signal, and for filtering a contralateral beamform signal into a contralateral bandpass beamform signal; a second beamforming module comprising an adaptive bandpass beamformer for provision of a second bandpass beamform signal; an adder for provision of a beamformed input signal; a processor for providing an electrical output signal based on the beamformed input signal; and a receiver for converting the electrical output signal to an audio output signal.
