Photophon Aernoudt Jacobs Jan 2013 - Sep 2013
Aernoudt Jacobs is doing research on the photoacoustic effect (in collaboration with KUL, Acoustics Lab) for the installation photophon. The photoacoustic effect is based on the phenomena of radiant energy. A strong light source can be converted into an acoustic wave due to absorption and thermal excitation. When rapid pulses of light are projected onto a sample of matter, they can be absorbed and the resulting energy will be radiated as heat. This causes sound waves due to pressure variations. The photoacoustic effect was discovered by Alexander Graham Bell in his search for a means of wireless communication.
photophon is produced by Intro in situ and opens in Maastricht in September 2013 and is part of Resonance, the European Sound Art Network.
