Observation of a Further Tartini Pitch Resulting from a Physical Sinusoid Added to a Tartini Pitch
Max F. Meyer · The Journal of the Acoustical Society of America · 1953
The sinusoidal air waves 9+6+2, shaking the skull, produce not only the commonly expected Tartini pitch 3 but also the rather surprising pitch 1, but none other. However, these occur only within a total range that barely encompasses the human voice. For this restriction a plausible evolutionary hypothesis suggested. The mathematical theory for the pitches 3 and 1 is furnished on the basis of a strictly hydraulic, i.e., nonvibratory, function of the cochlear phragma.
