Robust 3-D Crosstalk Canceller Design

It is well known that the effectiveness of loudspeaker-based 3D sound systems is critically dependent on the listener known position. Traditional approaches try to find the optimum loudspeaker location with least sensitivity to the listener movement, or to use multi-loudspeaker to reduce the effect of head movement. In this paper, we propose a region-based crosstalk canceller with only a pair of loudspeakers to provide increased robustness to perturbations such as head movement and head shapes. In the design of the crosstalk canceller, we propose a new common-pole model structure with reduced complexity.
