Abstract
Many of the noiselike sounds to which man is exposed serve to convey useful information and, under proper circumstances, allow the listener to make inferences about the source. A model of this discrimination process as one of feature extraction and decision making about the presence of salient features is proposed. The model and the signal patterns used in the experiment are restricted to features of the sounds which are dichotomous, i.e., present in one sound pattern and absent in the other of a pair of sounds to discriminate. A modified version of the classical threshold technique was employed in which the SNR of the signal increased through the course of a trial. Subjects were required to respond with their decision regarding which of two signals was presented with the broadband background noise. Results were analysed in terms of mean SNR to respond and probability correct. In general, the findings supported the proposed model.
