Resumo: In this paper we address sound source localization in the azimuthal plane. Various models, from the cochlear nuclei to the inferior colliculi, are implemented to achieve accurate and reliable localization. Coincidence detector cells in the medial nuclei and cells sensitive to interaural level difference in the lateral nuclei of the superior olive are combined with models of V-and I-type neurons plus azimuth map cells in the inferior colliculus. An advanced cell distribution in the inferior colliculus is proposed to keep ITD functions at any frequency within the physiological range of the head. Additional projections from the dorsal nucleus of the lateral lemniscus and the medial nucleus of the superior olive are modeled such that interaural time differences in different frequency bands converge to a single result. Experimental results demonstrate good performance in case of a variety of normal sounds.
