A Real-time Algorithm for Selection of Reference Microphone Pair in BLCMV Beamformers in Hearing Aids
The binaural linearly constrained beamformers are frequently employed in digital multi-microphone hearing aids. In this paper, a real-time algorithm for selecting the best reference microphone pair is proposed based on a study on the impact of reference microphone pair selection on binaural cue preservation for directional sources. The preservation of the binaural cues can be determined by the preservation of the Interaural Transfer Function (ITF) of the interfering signals for different reference microphone pair combinations. Based on realistic simulation-based experiments, the performance of the proposed algorithm is assessed.
