1. An apparatus comprising:
an input to receive input information, the input information comprising:
system bus information received via a system bus of a vehicle;
a plurality of noise inputs representing acoustic noise at a plurality of noise sensing locations; and
a plurality of residual-noise inputs representing acoustic residual-noise at a plurality of residual-noise sensing locations within a sound control zone in the vehicle;
a controller comprising logic and circuitry configured to determine a sound control pattern to control sound within the sound control zone in the vehicle, the controller configured to determine the sound control pattern based on the system bus information, the plurality of noise inputs, and the plurality of residual-noise inputs, wherein the controller is configured to determine a path transfer function setting of one or more path transfer functions based on the system bus information, and to determine the sound control pattern based on the path transfer function setting; and
an output to output the sound control pattern to a plurality of acoustic transducers.
