...Mag. S. 5. Vol. 27. No. 169. June 1889. 2 I which shows that in this case the intermittent vibration is equivalent to three simple vibrations of frequencies n, n + m, n — m. In order to distinguish wave-frequencies, whose difference is small, a correspond ingly long series...

...trigonometrical transformation (2) may be put in the form 2 cos 2irnt + cos 27r (n + m) t + cos 27r (n — m) t (3) ; which shews that the intermittent vibration...is the explanation of the secondary sounds observed byMayer. The form (2) is of course only a particular case. Another in which the intensity of the intermittent...
