T15 - Distance and Depth Perception

Durand Begault, NASA Ames Research Center - Moffett Field, CA, USA
William Martens, McGill University - Montreal, Quebec, Canada

Much discussion in the audio engineering literature has focused on the spatial location of sounds in terms of azimuth, and less often, elevation. Far less investigation has focused on auditory distance perception and how engineers consciously or unconsciously manipulate the relative distance of sound sources.
How is it possible for an engineer to systematically manipulate the distance of the perceived image of a sound source? How is the sound "stage" and relative distances established on both live and studio recordings? What are the fundamental cues for distance and depth perception? This tutorial seeks to elucidate these issues. Sound examples will be provided.
