Description
Ernst Chladni (1756-1827) was a German musician who studied the physics of sound. The Chladni Plate, one of his key inventions, was a flat piece of metal covered with a fine layer of sand; when a bow was drawn along one edge of the plate, the sand arranged itself in such a way that the nodal patterns became apparent.
This device consists of two circular brass Chladni plates held in an iron clamp. The Smithsonian Institution bought it in the 1860s, probably from Rudolph Koenig Paris.
