I found this video on a blog I read called open culture. I had heard a lot about these patterns, they are sometimes used in acoustic instrument making, but this is the first time I’ve actually seen it. These patterns called Chladni Patterns after Ernst Chladni who apparently invented this technique in the 1700′s.

The study of the visualization of sound is called Cymatics, here is an extract from an interesting article called Cymatics – The Art Of Sound by Katherine M.J. Osbourne.

“Cymatics and Music

Music is not a linear experience, it is four-dimensional. The sound is produce through the vibration of strings in roughly one dimension (the string has thickness). Surfaces and cavities (such as the body of a violin) vibrate in two and three dimensions. All the vibrations propagate in three dimensions through space. The air in a room filled with music is vibrating, and the shape and material of the walls also have resonant frequencies just as the instruments do. Cymatic visualization is used as a tool in acoustics to develop high quality instruments and sound systems. A movie theater outfitted with a THX or Dolby sound system has been optimized for a pleasurable aural experience by analyzing the building materials, placement of speakers, and other considerations.”

I find it very fascinating to be able to ‘see sound’. Even zooming in and seeing the wave-form representation in recording software is of endless entertainment to me. It amazes me the way something can be both so simple and so complex at the same time.

What do you think about visual representations of sound?
