Ernst Florens Friedrich Chladni was the first to devise a way to visualize the sounds transmitted by solid objects using sand. “He demonstrated the method by sprinkling sand on plates of glass or metal and drawing a bow down their sides to produce a visible vibration pattern called ‘Chladni figures.'”
Chladni published engraved images of these figures in a 1787 portfolio, Entdeckungen über die Theorie des Klanges., a first edition of which is to be auctioned at a sale of The Richard Green Library of Scientific Books, June 17 at Christie’s New York.
