Auditory Perception
Abstract
The experiments described were designed to measure how well the acoustic cues which are generally understood to be used for sound source segregation are processed by listeners who have more than the usual difficulty with that task. It is generally agreed that certain acoustic characteristics of competing signals are used by the auditory system for signal separation. These include coherence of amplitude modulation and coherence of frequency change across frequency, as well as similarity of a preceding signal with a delayed signal. We report here normative date for these tasks, which were collected on trained young subjects with normal auditory sensitivity. Based on the data produced by our experiments on signal separation, we conducted further experiments which verify our assumptions that these experimental paradigms do, in fact, reflect the signal separation abilities of the auditory system. Specifically, we have collected data on subjects with normal sensitivity who exhibit an unusual amount of difficulty listening in noise. The results of these experiments should be of interest in determining which of the several experimental paradigms thought to be related to signal separation are indeed necessary to performing that task.
