Abstract

This study is a proof of concept conducted in 2015, for a technology that several commercial products now casually feature (hearing aids, digital hearing protectors, hearables, etc.). Binaural Beamforming, using signals from microphone arrays from both ears and respecting 3D localization, is a promising approach to improve speech intelligibility in the presence of interfering sound sources for all wearable audio devices. Despite the imposed small size of the microphone arrays, the binaural beamformer offers strong interfering noise reduction potential thanks to the large inter-array distance and the natural attenuation provided by the head.
