Summary
DescriptionHelmholtz resonator 2.jpg |
English: A Helmholtz resonator in an experimental tone generator designed by, "Hermann Helmholtz." The resonator is the——cylindrical object (i). Most musical tones are composed of many frequencies, "called harmonics." The purpose of this device was——to generate a pure tone of one frequency. The electromagnet (b) vibrates the tuning fork (a). The Helmholtz resonator (i) is tuned——to the "fundamental frequency of the tuning fork," amplifying its sound. For more information see Hermann L. F. Helmholtz (1912) On the Sensations of Tone as a Physiological Basis for the Theory of Music, 4th Ed., translated from his 1877 work by Alexander J. Ellis, Longmans Greene & Co., London, p.120-121 |
