Abstract

Viene descritto un sistema per la rilevazione e la localizzazione di segnali acustici utilizzabile ad esempio per l'acquisizione di messaggi vocali, o di altro tipo, in ambienti presentanti rumore, echi e riverberi. Il sistema permette inoltre la ricostruzione di messaggio acustico (RS) depurato dalle componenti, dovute a rumore, echi, etc., indesiderate.Per svolgere tali funzioni il sistema impiega una schiera di microfoni (P0, P1, P2, P3) e si basa sul calcolo dell'antitrasformata di Fourier della sola informazione di fase dello spettro di potenza normalizzato incrociato (Y1, Y2, Y3) di coppie di segnali (S0, S1, S2, S3) acquisiti dai microfoni della schiera (P0, P1, P2, P3).(Figura 1)
