Binaural localization.

In this paper we review some issues which are relevant to the formation of special positions and extents of auditory events in the case of two normally functioning ears. Physical aspects under consideration are measurement and analysis of the transfer functions of the external ears. These transfer functions are responsible for encoding information about the spatial characteristics of sound fields into the ear input signals. The hearing system can decode this information by evaluating interaural and monaural cues of these signals. A rough outline of psychoacoustical effects and mechanisms involved in this evaluation is given and a conceptual model of binaural interaction is described.
