摘　　要：The objective of acoustic crosstalk cancellation is to use loudspeakers to deliver prescribed binaural signals(that reproduce a particular auditory scene) to a listener's ears, which is useful for 3-D audio applications.In practice, the actual transfer function matrix will differ from the design matrix, because of either the listener's head movement or rotation, etc. Crosstalk cancellation system(CCS) is very non-robust to these perturbations. Generally, in order to improve the robustness of CCS, several pairs of loudspeakers are needed whose position varies continuously as frequency varies. With the help of assumed stochastic analysis, we propose a stochastic robust approximation crosstalk cancellation method based on random perturbation matrix modeling the variations of the transfer function matrix. Under the free-field condition, simulation results demonstrate the effectiveness of the proposed method.The objective of acoustic crosstalk cancellation is to use loudspeakers to deliver prescribed binaural signals（that reproduce a particular auditory scene） to a listener＇s ears, which is useful for 3-D audio applications.In practice, the actual transfer function matrix will differ from the design matrix, because of either the listener＇s head movement or rotation, etc. Crosstalk cancellation system（CCS） is very non-robust to these perturbations.
