Model of Temporal and Spatial Factors in the Central Auditory System

Abstract

In this chapter, a workable neuropsychological signal processing model is proposed that links temporal and spatial acoustic factors with their corresponding perceptual attributes via observable response properties of the central auditory system. In the model, temporal factors that are observed to be associated with left cerebral hemisphere responses may be extracted from central autocorrelation processors. Similarly, spatial factors observed to be associated with the right hemisphere may arise from the action of central binaural crosscorrelators in the auditory pathway. Thus, the subjective attributes of sound fields can be described in terms of these temporal and the spatial factors and their corresponding specializations in the two cerebral hemispheres.
