Spatial Sound Localization Measures From a Dummy Head with a Loudspeaker Array in Anechoic Chamber

In videoconference systems composed of microphone and loudspeaker arrays, a cue of subjective sound quality is the ability to locate the sound source. A ten loudspeakers array and a dummy head are implemented in an anechoic chamber. The field sampled by the microphone array is simulated by a narrow band source located at different azimuths. That simulation is emitted by the loudspeakers array and the binaural signal from the head is processed. Some improvements have been made in previous methods of azimuth estimation. The ellipsoidal head model used to calculate the interaural time difference (ITD) gives better results. The estimation given by the ILD (Interaural Level Difference) cue is used to avoid the ITD ambiguity at high frequencies.
