Excerpt from Combination Tones and Other Related Auditory Phenomena: A Dissertation Submitted to the Faculty of the Graduate School of Arts and Literature in Candidacy for the Degree of Doctor of Philosophy, Department of PsychologyIn the pages which follow several physical terms are used which are commonly understood and need no definition here. A few may be new to readers not familiar with the literature of acoustics. A pendular (or pendulum) vibration is a simple, or sinus-form, vibration. In several quotations the wor note, and sometimes sound, occurs where the mean ing is precisely that of the word tone. Interruption tone is used synonymously with intermittent tone. By transformation of the primaries is meant the process of superposition of vibrations explained by Helmholtz in his mathematical determination of the origin of combination tones. A combination tone may, of course, be either a difference tone or a summation tone.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
