A Dual-Layer Beamforming Module with Computer Vision Function for 3d Space Perception

Abstract
Users often hesitate to adopt assistive listening devices (ALDs) due to concerns about accurately perceiving sound positions and potential risks. Our study proposes a novel method in the ALD's space perception module, integrating computer vision technology (CV), a dual-layer beamforming module, a dual-layer differential microphone arrays algorithm (d-DMA), and time difference of arrival (TDOA). Primarily designed for individuals, a successful prototype addresses existing limitations, opening avenues for future advancements.
