A Study of Psychoacoustics in Passive Sonar Classification. Part 2. A Review of General Concepts and A Discussion of Results Obtained to Date.
Abstract
This report reviews relevant knowledge in the context of passive sonar aural recognition of a noise source, and defines an experimental approach to extend the state of knowledge in areas of immediate concern to the Naval Air Systems Command. The report is prepared in two parts with Part 1 summarizing the sonar classification task and then leading into the relationships of this task to the general topic of acoustic warfare. Part 2 of the report considers the aural classification task in more general terms. The results of studies using trained listeners are presented and are compared to those predicted from previous studies done elsewhere. A model of the classification task as a specialized detection problem is presented and it is shown that the model allows prediction of the results within a few dB of signal-to-noise ratio required to make a terminal classification decision.
