The performance of two-channel transaural sound reproduction systems has been assessed with respect to the form and size of the crosstalk cancellation zones for different loudspeaker arrangements. Channel separation has been measured for small displacements of a dummy head in the horizontal plane around the point of optimal crosstalk cancellation. Behavior of the system in different frequency bands and for loudspeakers arrangements with different angular separations has also been considered. The experimental study has been compared with computer simulations based on models of the transaural sound reproduction system, with and without consideration of the acoustic scattering produced by the human head. Experimental results point toward the importance of including the acoustic scattering of the human head in computer simulations and that it is a very important factor in the design of transaural systems. This work has also provided some useful guidelines for practical implementations of 3-D sound reproduction systems.:
