Abstract

The invention concerns a system for processing a sound signal comprising an amplifier, an analog-to-digital conversion circuit or a digital-to-analog conversion circuit, a filtering circuit, end processing elements and a circuit for adding filtered signals, so as to deliver at least an output signal, said end processing elements being sound sensors or loudspeakers. The invention is characterized in that the filtering circuit is optimized in accordance with the characteristics particular to the end processing elements and in accordance with their geometric implantation and it comprises at least a directive lobe and an output circuit delivering an output signal through directive lobe.
