Chladni Cast (830 Hz)
A Chladni Cast subjects form work to sustained vibrations during the curing process to study how audible frequencies affect the manner in which concrete sets. This research might be seen as an elaboration upon the plate experiments of Ernst Chladni, in which the modes of vibration of a rigid surface were made visible by sprinkling salt upon a resonating steel plate.
The Chladni Cast shown here was cast upon a Chladni Plate organization of aggregate that collected on the nodal lines of a steel plate vibrated at 830 Hz.
