Prepared at the Institute for Perception Research (IPO), Eindhoven, The Netherlands. Supported by the Acoustical Society of America (ASA). Northern Illinois University DeKalb, IL, USA (NIU) also participated in the making of the release.
The 39 demonstrations on this CD have been put on separate tracks. Demonstrations in Sections I through VI have been designed for typical classroom use. The demonstrations of Section VII must be heard through headphones to obtain the desired effects.
Updated reissue of the 1978 set of auditory demonstration tapes released by the Laboratory of Psychophysics of Harvard University. The tape set contained 20 recorded demonstrations of psychoacoustics plus an explanatory booklet and sold out quickly.
Jewel case inside a cardboard slipcase. Contains a separate 92-page booklet with introduction, contents, detailed explanations of each demonstration, illustrations, technical information, comments and references.
