We made a Tonocope to see Chladni figures on its surface. Sometimes this device is known as a Cymatics visualiser. It's purpose it to visualise the vibrations on the surface, when it is excited/driven by sound.
A mathematician named Ernst Chladni first demonstrated the types of patterns that appear on a rigid surface, when being vibrated. The patterns occur on the surface at different frequencies, which vary from surface to surface, depending on its geometry.
This kind of acoustic phenomenon is still used to today in musical instrument design and a similar principle is used for acoustic room design.
