Watch a voice-driven Chladni plate! Sound pioneers Robert Hooke and Ernst Chladni discovered in the 18th and 19th centuries that sand scattered on a glass or metal plate sent into resonant vibration with a violin bow arranges itself into interesting patterns according to places of stillness. Chladni plates are today often driven by tone generators and used in scientific demonstrations of modes of vibration, but Meara will also show how the human voice and various speech sounds have resonances of their own.
