Auditory demonstrations on compact disc

In 1984, the Committee on Education in Acoustics of the ASA discussed the possibility of reissuing the “Harvard Tapes,” a series of audio demonstrations on tape cassettes originally published in 1978 by David M. Green at the Harvard Laboratory of Psychophysics. The present authors undertook the job of evaluating and updating the content of the original tapes, producing new audio material, and writing a new explanatory book. The compact disc (CD) medium was chosen to replace magnetic tape. Through substantial cooperation from Eindhoven University of Technology, Northern Illinois University, the Philips Company, and the ASA, a CD with a 92‐page booklet was developed containing groups of auditory demonstrations divided over seven general topics. For each group, a general introduction with basic references is provided in the booklet. For each demonstration within a group a detailed background, explanation and further literature references are given. Verbal introductions on the CD have been kept very brief and serve mainly to identify each demo. Demonstrations or parts thereof can be called individually in any order, or preprogrammed in arbitrary groups, through 80 separate track or “title” numbers. One thousand copies of the CD set have been made on a first production run. They are available through the headquarters of the ASA.A CD player with the auditory demonstration will be available at the registration desk for the entire meeting.
