Beamforming headphone ANC for targeted noise attenuation

A novel Targeted through Beamforming Active Noise Control (TBANC) approach for headphones is presented which achieves an improved noise reduction via targeting of a specific, potentially disturbing noise source in the presence of the di?use field noise interference which is addressed by current ANC methods. The method utilizes the signals captured by two reference microphones, one on each headphone earcup, in a multi-reference ANC scheme while a phased array is formed by these two microphones that commonly reside on top of the headphone earcups. By employing a simple Time-Delay Beamforming approach to target the primary, undesired noise source, the proposed ANC successfully attenuates this source while also achieving a significant reduction of the di?use noise.
