An Experimental Treatment of Auditory Discrimination of Complex Noise-Like Sounds.
Abstract
This thesis deals with an attempt to quantify subjective responses to sounds, especially in the discrimination between similar sounding noise-like stimuli. A model of the discrimination process as one of feature extraction and decision making about the presence of salient features is proposed. Experiments using both marine sounds and laboratory generated signals were conducted using trained University student listeners and Navy personnel. Two experimental methods were applied with one using a modification of classical threshold techniques. The other procedure used a continuous rating scale to elicit information about the confidence of the listener's discrimination decision.
