Abstract

This paper proposes a time-domain multi-channel directional active noise control (ANC) system to reduce noises selectively based on the direction of arrival (DOA). This system consists of three subsystems: the beamforming subsystem, the ANC subsystem, the sound reproduction subsystem. The beamforming subsystem is implemented to capture the desired sound for the sound reproduction subsystem. The ANC subsystem is developed to reduce noises from all directions and the sound reproduction subsystem is implemented to reproduce sound from the desired direction. As a preliminary work of directional spatial ANC, the proposed system enables the user's ears at error microphone locations hearing the desired sound with reduced noises without wearing headphones. The simulation results demonstrate that our system can reduce noises significantly and preserve the desired sound from desired direction, where the binaural localization cues of the desired sound is also preserved.
