Effect of loudspeaker position on the robustness of acoustic crosstalk cancellation

Acoustic crosstalk cancellation is a signal processing technique whereby tw o (or possibly more) loudspeakers are used to deliver desired signals exact ly at the listener's ears. Such a system is useful for three-dimensional (3 -D) audio applications, and removes the requirement for the listener to wea r headphones. However, crosstalk cancelers are notoriously nonrobust to sli ght movements in head position, Recently, a system consisting of two closel y spaced loudspeakers (referred to as the "stereo-dipole") has been propose d to improve the robustness of the crosstalk canceler. in this letter we pr esent a robustness analysis of the two-channel crosstalk canceler, and deri ve optimum loudspeaker positions.
