Patent ID: 11862139

Abstract:
A method and a system for creating a plurality of sound zones within an acoustic cavity is provided. The method comprises: providing a plurality of actuators within the acoustic cavity, each for generating a respective acoustic output in response to a respective drive signal, providing, for each of the plurality of actuators, an adaptive filter for receiving a respective input signal, and generating a respective output signal, providing, for each of the adaptive filters, at least one filter coefficient, providing a plurality of error sensors within the acoustic cavity, each for generating a respective error signal e, representing a respective sound detected by the respective error sensor, providing an audio data signal x(n) for generating a desired sound in a desired sound zone of the plurality of sound zones, determining, for the desired sound zone, a set of actuator generation coefficients kgk, a set of actuator exclusion coefficients kek, wherein k refers to a kth actuator, k=1, 2, 3 . . . , and a set of sensor weighting coefficients mem wherein m refers to a mth error sensor, m=1, 2, 3.
