ABSTRACT:
Said method for control of a reproduction unit (2) for an acoustic field with a number of reproduction elements (31to3N) is characterised in comprising: a step for establishing a finite number of coefficients representative of the temporal distribution and in the three spatial dimensions of said acoustic field, a step for determination of representative reconstruction filters for said reproduction unit (2) and at least the spatial configuration of said reproduction unit (2); a step for determination of at least on control signal (SC1to SCN) for said elements (31to3N) by the application of said coefficients to said reconstruction filters and a step for providing said at least one control signal for application to said elements (31to3N) for generation of said acoustic field for reproduction.
