Conducting nonadaptive psychoacoustic or biomedical tests by means of an interactive program

Abstract

The program described in this paper was originally designed to generate the (synthetic) stimuli required for a large class of psychoacoustic tests. In our opinion, however, it may also be of interest in other fields of biomedical information processing. The applied computational techniques are standard in the field of digital signal processing, but the program is particular in its way of presenting signals, executing window operations, and describing the decision blocks to be presented during a test. Each decision block is a succession of stimuli and pauses, presented to obtain one judgement from the subject.
