Chladni Cast (175 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 in form work that was supported in its center by a transducer which blasted a 270 Hz tone during the curing process.
