Previous Next Auditory Demonstrations # 3C10.001
Description: In 1978, a set of auditory demonstration tapes was released by the Laboratory of Psychophysics of Harvard University. These demonstrations had been prepared by a team led by Prof. David M. Green and were sponsored by a grant from the National Science Foundation. The set contains 20 recorded demonstrations on psycoacoustics plus an explanatory booklet. Instructions: CONTENTS Section I. Frequency Analysis and Critical Bands Cancelled Harmonics Critical Bands by Masking Critical Bands by Loudness Comparison Section II.
