Binaural model for artificial spatial sound localization based on interaural time delays and movements of the interaural axis

Kneip, Laurent; Baumann, Claude


This paper presents a mathematical model for sound localization in space using two-microphone devices that possess at least two degrees of freedom. It proves a series of theorems and lemmas that are based on time difference of arrival measurements and movements of the interaural axis, forming a powerful instrument for practical robot applications. For instance, it shows that a single determined rotation of the interaural axis is sufficient to exactly yield the azimuth or the elevation of an...[Show more]
