Binaural sound source localization consists in estimating the position of a sound source with respect to a single pair of stationary microphones.

Abstract
Binaural sound source localization consists in estimating the position of a sound source with respect to a single pair of stationary microphones. A possible implementation of binaural localization exploits the information contained in two physical cues: the Interaural Time Difference (ITD) and the Interaural Level Difference (ILD). A recent paper [1] described a novel approach to binaural source localization based on a joint ILD-ITD estimation. The present work describes the effect of acoustic reverberation on this method. As expected, reverberation adds uncertainty to the localization process, thusmaking it necessary to introduce proper prefiltering techniques. © 2011 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
