Loudspeaker distributions suitable for crosstalk cancellers robust to head rotation

Loudspeaker distributions resulting in crosstalk cancellers robust to head rotation are identified. A series of computer simulations were conducted to evaluate the resulting binaural signals of crosstalk cancellers for various loudspeaker configurations. 52,650 different two-channel loudspeaker arrangements were considered and the crosstalk cancellation filters were calculated using the time-domain least-squares method. When the head orientation was not exact, the resulting signals for the higher ranked loudspeaker arrangements were found to be more similar to the ideal impulse and null signals than those for the lower ranked loudspeaker configurations. Results show that crosstalk cancellers that use the higher ranked loudspeaker arrangements are regarded to be more robust to head rotation than those designed for other loudspeaker configurations.
