METHOD AND DEVICE FOR CONTROL OF A UNIT FOR REPRODUCTION OF AN ACOUSTIC FIELD

Abstract A method of controlling a reproduction unit (2) for restoring an acoustic field so as to obtain a reproduced acoustic field of specific characteristics substantially independent of the intrinsic characteristics of reproduction of said unit (2), said reproduction unit (2) comprising a plurality of reproduction elements (31 to 3N), characterized in that it comprises at least: a step of establishing a finite number of coefficients representative of the distribution in time and in the three dimensions in space of said acoustic , field to be reproduced; , a step (50) of determining reconstruction filters representative of said reproduction unit (2), comprising a substep (54) of taking into account at least spatial characteristics of said reproduction unit (2) ; a step (70) of determining at least one control signal (SC1 to SCN) for said elements (31 to 3N) of said reproduction unit (2), said at least one signal being obtained by the application, to said coefficients, of said reconstruction filters; and a step of delivering said at least one control signal (SC1 to SCN) , with a view to an application to said reproduction elements (31 to 3N) so as to generate said acoustic field reproduced by said reproduction unit (2).
