Claim 8:
9. The method for creating a plurality of sound zones within an acoustic cavity as claimed in claim 2, wherein the optimization process comprises:
determining the set of actuator exclusion coefficients kek, and the set of sensor weighting coefficients mem, by minimising the following function

<emonitors2>σd+α<|emonitors−dmonitors|2>σb,

wherein <emonitors2>σd refers to a squared pressure level of a third sound outside the desired sound zone, generated by the plurality of the actuators;
wherein α<|emonitors−dmonitors|2>σb refers to a squared pressure level difference between a fourth sound within the desired sound zone and the first sound within the desired sound zone; and
wherein α is a weighting factor, which is a positive real number.
