PHOTOPHONE PRINCIPLE & Prototypes

next

The Photophon Principle is based on the photoacoustic principle that was discovered at the end of the 19th century by Alexander Graham Bell. According to this principle, a strong light source can be converted into an acoustic wave due to absorption and thermal excitation. Bell's research shows that any material comes with a sonority that will be revealed by hitting it with a strong beam of light. In the exhibition a prototype of the original work will be shown to illustrate this principle. The prototype consists of a photophonic object playing tones created by strong light beams through a rotating disc. With The Photophon Principle, Jacobs intends to provide a certain kind of musicality: "but in the form of an installation, not of a playable instrument", he explains.
