Fig. 2From: Speech enhancement for multimicrophone binaural hearing aids aiming to preserve the spatial auditory sceneSchematic of beamforming with binary decision mask. The multichannel input signal is converted into the time-frequency (T-F) domain and then passed to the binaural spatial filtering algorithm. The binary decision mask, based on the SNR estimator, then either passes the output signals of the binaural spatial filter or the scaled reference microphone signals to the in-ear transducersBack to article page
