Physical Factors in Auditory Perspective
John C. Steinberg, William B. Snow · Journal of the Society of Motion Picture and Television Engineers · 1953
In considering the physical factors affecting it, auditory perspective is defined in this paper as being reproduction which preserves the spatial relationship of the original sounds. Ideally, this would require an infinite number of separate microphone-to-speaker channels; practically, it is shown that good auditory perspective can be obtained with only two or three channels.
