Experimental evaluation of cross-talk cancellation regarding loudspeakers'angle of listening

The reproduction of three-dimensional (3-D) sound (either from binaural rec ordings or virtual source synthesis) through loudspeakers, also known as tr ansauralization, adds difficulties to the traditional method using headphon es: the cross-talk effect between speakers and the listener's ears must be taken into account. The common way of removing this distortion consists of placing a filter bank before reproduction through the loud-speakers, but th ese crosstalk cancellers are notoriously nonrobust to slight movements of t he head. Recent theoretical works studied the influence of loudspeaker posi tions relating to robustness of the system. This paper presents a series of experiments that validate the theory and add new ideas for the design of c rosstalk cancellers.
