Chladni Cast (315 Hz - 630Hz)
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 subjected to sustained vibrations at 315 Hz with punctuated bursts of 630 Hz.
