Abstract
The invention proposes a method for improving the spatial hearing perception of a binaural hearing aid, said binaural hearing aid comprising a first local unit and a second local unit, wherein in the first local unit, a first input signal is generated from an environment sound by a first input transducer, and a first reference signal is derived from the first input signal, wherein in the second local unit, a second input signal is generated from the environment sound by a second input transducer, and a second reference signal is derived from the second input signal, wherein from the first reference signal and the second reference signal, a first binaural beamformer signal is derived, wherein from the first reference signal and the first binaural beamformer signal, a first coherence parameter is derived, wherein from the first coherence parameter, a first mixing parameter is derived, and wherein the first reference signal and the first binaural beamformer signal are mixed by means of the first mixing parameter in order to generate a first output signal.
