Listener-perspective-dependent variation of interaural cross-correlation coefficient in a reverberant space

This paper presents an extensive set of IACC measurements using BRIRs obtained at 16 different positions in a reverberant concert hall, each with 100 rotation angles. The results show the variation of IACC relative to the listening positions and head rotations, for both early and late reflections. It was found that the variation of IACCE3 (< 80ms) depending on the position had some consistent patterns with the relative head orientation to the sound source. However, it was observed that, near the side wall, the variation of IACCE3 showed a higher consistency with the head rotation relative to the direction of the wall. The measurements of IACCL3 (> 80ms) revealed that values recorded outside the central axis of the room were influenced neither by the head rotation nor the position in the room.
