A Bayes-rule based hierarchical system for binaural sound source localization

Research output: Contribution to journalConference articlepeer-review


A Bayes-rule based hierarchical binaural sound source localization system is proposed. By combining three localization cues: interaural time differences (ITDs), interaural intensity differences (IIDs), and spectral cues, and a hierarchical decision making structure, this system enables to locate a sound source in a 3D space by using only the binaural inputs. Preliminary simulations have shown the effectiveness of this system. It can be used in studying binaural localization mechanism and applications such as in hearing aids and robotics.
