Abstract
A hearing device for a binaural hearing system comprising the hearing device and a contralateral hearing device, comprising: a transceiver module for obtaining a contralateral filtered beamform signal from the contralateral hearing device; microphones for provision of a first and second microphone input signals; a first beamforming module for provision of a first beamform signal based on the first and second microphone input signals; a filter bank, connected to the first beamforming module, for filtering the first beamform signal into a plurality of filtered beamform signals including a first bandpass beamform signal; a bandpass beamformer coupled to the filter bank; an adder, connected to the bandpass beamformer, for provision of a beamformed input signal; a processing circuit for processing the beamformed input signal and 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.
