Optimal crosstalk cancellation filter sets generated by using an obstructed field model and methods of use

A method of providing a crosstalk cancellation filter set, the crosstalk cancellation filter set being configured for use in delivering binaural signals to human ears in an obstructed free field, the method comprising:

• configuring a spherical head model for communication with a pressure matching system;
• and
• configuring the pressure matching system to perform spatial filtering or sound field control based on an acoustic shadowing effect caused by a human head and a time delay effect caused by the human head;
• wherein a propagation is computed considering a driver and control points using a numerical approximation of a Rayleigh solution for an acoustic pressure on a rigid sphere.

One or more non-transitory, machine-readable media having machine-readable instructions thereon which, when executed by one or more processing devices, cause the one or more processing devices to perform operations comprising:

• configuring a spherical head model for communication with a pressure matching system;
• and
• configuring the pressure matching system to perform spatial filtering or sound field control based on an acoustic shadowing effect caused by a human head and a time delay effect caused by the human head;
• wherein a propagation is computed considering a driver and control points using a numerical approximation of a Rayleigh solution for an acoustic pressure on a rigid sphere.
