Abstract

This paper seeks to pinpoint the optimal loudspeaker span that best reconciles the robustness and performance of the crosstalk cancellation system (CCS). Two sweet spot definitions are employed for assessment of robustness. Besides the point source model, head related transfer functions are employed in the simulation to capture more design aspects in practical situations. Three span angles, 10 degrees, 60 degrees, and 120 degrees, are compared via objective and subjective experiments. Analysis of Variance is applied for analysis. The results indicate that not only the CCS performance but also the panning effect and head shadowing will dictate the overall performance and robustness. The 120-degree arrangement performs comparably well as the 60-degree arrangement, but is more preferred than the 10-degree arrangement.
