photophon #1 is an installation based on intensive acoustic research of the photoacoustic effect. The photoacoustic effect is based on the phenomena of radiant energy. A strong light source can be converted into a sound wave due to absorption and thermal excitation. This causes sound waves due to pressure variations. The photoacoustic effect was discovered in the 19th by Alexander Graham Bell. He then used candlelight, sunlight, and the first forms of electricity in order to amplify sound.
