Helmholtz Resonator Bank	helmholtz spheres - largest and smallest

Description:

Set of fourteen Helmholtz resonators numbered from the largest 150 in increasing jumps of 50 to the smallest numbered 800. Herman von Helmholtz (1821-1894)was appointed professor of physiology at the university of Königsberg and studied physiological acoustics and optics. He moved to Heidelberg in 1858, and there wrote a treatise on sensory acoustics as the basis for the theory of music. He conceived the rod-like features in the ear as tuned resonators, which he modeled. To test the presence or absence of a particular harmonic in a given musical tone, a resonator in tune with the harmonic is put to the ea, and if the resonator 'speaks', it proves that the harmonic is present. (reference the Teyler Museum, Netherlands Gerald L'E Turner). The largest sphere is 10.5" (267 mm) high x 9" (229 mm) diameter, the smallest is 2.48" (63 mm) high x 1.875" (47 mm) diameter. The wood base is 8.5" (210 mm) x 30" (762 mm).
