Spatially selective binaural hearing AIDS

Traditional hearing aids are limited by the absence of spatial selectivity. Superdirective microphone array can recover such limit, performing a spatial filtering to achieve an augmented SNR. We present Glassense, a platform hosting a double microphone array connected to a processing unit and mounted on the frame of common glasses. The platform has the potential of delivering binaural spatially selective audio inputs, allowing ecological pointing of acoustic sources through head motion. The designed microphone arrays exhibit a gain suitable to improve the speech reception threshold of hearing-impaired subjects, obtained on a lightweight and scalable hardware setup
