Abstract (en)
[origin: EP3148217A1] The invention relates to a method (18) for operating a binaural hearing system (20), said binaural hearing system (20) comprising a first hearing aid (24) and a second hearing aid (26), wherein the first hearing aid (24) generates a first reference signal (28) from a sound signal (22) by a first microphone (30), wherein the second hearing aid (26) generates a second reference signal (32) from a sound signal (22) by a second microphone (34), wherein the first reference signal (28) and the second reference signal (32) are both used to derive a first binaural beamformer signal (46) and a second binaural beamformer signal. Furthermore, the first reference signal (28) and the second reference signal (32) are used to determine a common gain (48), and from the first reference signal (28) and the common gain (48) a first common gain signal is derived (50), and from the second reference signal (32) and the common gain (48) a second common gain signal is derived, wherein at least for a number of frequency bands the first binaural beamformer signal (46) is compared with the first common gain signal (50) for classification (56) with respect to a noise reduction, and the first binaural beamformer signal (46) and the first common gain signal (50) are mixed in dependence of said classification (56) in order to obtain a first output signal (58).
