Multiple Listener Crosstalk Cancellation Using Linear Loudspeaker Arrays For Binaural Cinematic Audio

Crosstalk cancellation can be used to reproduce binaural audio over loudspeakers without headphones. This is desirable for use in a cinema, where current surround sound systems do not produce a consistent spatial experience for the majority of listeners across the auditorium. A crosstalk cancellation system for three listeners using loudspeaker arrays is proposed. The system’s ability to provide crosstalk cancellation is assessed through numerical simulations. Identical systems are placed either side of the central system, mimicking the row of a cinema, and the issue of acoustic leakage from the neighbouring systems is negated by including control points at neighbouring listener positions. Finally, an optimal control point assignment, allowing for the placement of crosstalk cancellation systems side by side, is presented.
