Media Technology assistant professor and artist Edwin van der Heide exhibits his "Sound Modulated Light #3" project as part of the exhibition "Sound Art. Klang als Medium der Kunst" at ZKM | Zentrum für Kunst und Medientechnologie.
Sound Modulated Light is an environment of light and sound wherein sound is not present acoustically, but is carried by light. The space consists of a design of multiple lights. Each light bulb has its own soundtrack assigned to it. The sound is modulated on top of the light by means of intensity modulation. Low audio frequencies result in a visible flickering of the lights. Higher audio frequencies result in a flickering that is too fast to be perceived by our eyes.
The ZKM | Zentrum für Kunst und Medientechnologie (Center for Art and Media) in Karlsruhe, Germany is an interdisciplinary art museum and research institution focusing on new media. The "Sound Art. Klang als Medium der Kunst" exhibition runs from March 17 2012 until January 6 2013.
