Binaural Processing of Complex Stimuli.

Abstract

Sounds produced by acoustic sources are localized and detected on the basis of differences in the time of arrival between the two ears and differences in the levels at the two ears. Most real world sounds are spectrally complex, consisting of energy distributed across many frequencies. In general, the auditory system must make judgments regarding the location of acoustic sources on the basis of these interaural differences, even though their distribution across frequency may be quite complex. This proposal has sought to understand the processes by which the binaural auditory system combines interaural information across the spectrum. The auditory system is spectrally synthetic, averaging information across the frequency domain, when the signal consists of relatively few components. Under these circumstances, the system behaves as though all components arise from the same spatial location.
