Popis: Vibration mode of the human skull was studied by means of holographic interferometry. Three dry human skulls were vibrated with generated bone-conduction receiver for several test frequencies within audible range.After assessing resonance frequencies on each skull, holograms of the vibrating skull were recorded and reconstructed in each resonance frequency principally.Vibration of the skull was clearly discernible not only at the vibrated temporal surface but also the opposite side.Noteworthy findings were vibration fringes on the temporal surface observed at the test frequencies of 400Hz and 100Hz, suggesting a possible component of compression bone-conduction at such low frequency ranges.
