ABSTRACT
I must admit that the visual system is about a hundred times more sensitive to differences in source location than is the auditory system, and the visual system can accurately determine the shapes of objects, which is largely impossible for the auditory system. However, our eyes are limited in their field of view, whereas our ears are sensitive to sounds from any direction and from sound sources that may be hidden behind other objects. Much information about approaching danger comes from sound, not light. This chapter describes how the auditory system localizes sounds and how it deals with the problems of sound reflection in which the direction of a sound waveform does not correspond to the location of the original source. We also consider how sound reproduction can be made more realistic by incorporating spatial cues.
