ABSTRACT:
This system for determining a representation of an acoustic field (P) includes:acoustic wave acquisition elements (1) including a plurality of elemental sensors (21to2Q) which are distributed in space and which each deliver a measurement signal (c1to cQ); andelements (8) for processing by the application, to the measurement signals (c1to cQ), of filtering combinations representative of structural characteristics of the acquisition elements (1) in order to deliver a plurality of acoustic signals (sc1to scN) which are each associated with a predetermined general reproduction direction defined relative to a given point in space (14), the set of acoustic signals (sc1to scN) forming a representation of the acoustic field (P). The system is characterized in that the elemental sensors (21to2Q) are distributed in space in a substantially non-regular manner and in that the filtering combinations are representative of that distribution.
