Effects of an Artificial Head and a Cross-talk Insulating Material on Interaural Cross-correlation in Stereo Sound Reproduction System
Takamasa Ota, Kenji Furihata (Shinshu Univ.) EA2010-69
Abstract (in Japanese) (See Japanese page) 
(in English) A two-channel sound reproduction system (stereo) has a crosstalk. Therefore, doing away with such stereo crosstalk is essential to achieving high fidelity sound reproduction. The simplest form of crosstalk cancellation using a physical barrier – an absorbent vertical wall extending from the listener toward two loudspeakers placed just slightly further apart than the width of the barrier. In this paper, an physical barrier (an insulation material; reticulated polyurethane foam, width; 1.0m×height; 0.5m×thickness; 0.08m) was experimentally discussed whether eliminating crosstalk to improve sound reproduction is effective. From the results of the inter-aural cross-correlation (IACC) measured by two microphone method and an artificial head, it can be found that the relationship (the correlation coefficient) between the delay time of the 2 channel input signals and the IACC (τIACC) measured using the insulating material and the artificial head is 0.9903.
