On the performance and robustness of crosstalk cancelation with multiple loudspeakers

Acoustic crosstalk cancelation is a signal processing technique that uses two or more loudspeakers reconstruct the acoustic pressures at the listener's ears. The crosstalk arises because each speaker sends sound to the ipsilateral ear, as well as undesired sound to the contra lateral ear. Taking crosstalk cancelation technique can deliver desired signals exactly at the listener's ears that would result from the natural listening situation to be simulated and using crosstalk cancelation technique people can enjoy spatial audio without wearing a headphone. Classical crosstalk cancelation systems (CCS) employ only two loudspeakers, and their performance is usually unsatisfactory in practice. While the idea of using more loudspeakers has been investigated, we design a new 3-channel system to improve the performance on sound separation and robustness to head. The simulation results indicate that multichannel loudspeaker can improve the performance and the robustness of three-dimensional (3D) audio system.
