Determination of Multiple Sound Sources

Abstract

The results studied showed that the SALT procedure produced weights that were much more consistent with subject reports than threshold measures. That is, the change in weights with increasing stimulus duration for the lateralization task indicated that the tones become more separable (analytic listening) as the overall duration increases. This does not occur with traditional measures of thresholds. In the amplitude modulation task, the modulated tones become more separable (analytic listening) as the modulation rates of the targets and distractor differ. Again traditional measures using thresholds do not show the same trend. Subjects also report that the modulated tones are different when the rates differ.
