This is the visualized sound of Michael Patrick Kelly's famous #PeaceBell. Recorded by sound artist Dirk Schulz and brought into vision using a special cymatic technique (sound to image).
 
Here you can clearly see the frequency energy of the bell sound moving from left to right, with the lower beams of light representing the lower frequencies and the upper beams representing the higher harmonics vibrating above the fundamental.
 
Two sizes are available. 40x60cm | 60x80cm This print is a frameless, modern, high quality foam print with excellent color intensity and does not reflect light or objects like an ordinary glass frame. It comes with wall mounts already installed and is ready to use straight out of the box. 
 
The unique sound to image technique The sound designer and artist Dirk Schulz uses special techniques to bring the sounds & tones into an extraordinary visual perspective. He works with a complicated setup of high-end studio equipment and special software.
