In a typical psychoacoustic experiment, acoustic stimuli are presented to human subjects and the subjects are instructed to perform a behavioral task and generate responses accordingly. For example, in order to study the subject’s hearing sensitivity at a certain frequency, a pure tone at this frequency could be presented to the subject, and the subject’s task is to indicate whether the pure-tone stimulus is audible by either raising his or her hand or pressing a corresponding button.
