Heliophone Sunlight Sound

Heliophone 02 THUMB.jpg

IDEA: Turn sunlight into sound without electronic amplification.

WHAT: The installation uses Bell's photo-acoustic principle. It follows the trajectory of the sun, catching the sunlight and focusing it, via a parabolic lens, onto one point. A rotating disk chops the light up into small fragments. A photo-acoustic cell transforms these fragments into sound, made audible by a large horn. The tonality of the installation changes with the intensity of light.

WHY: A notion of ‘environmental sounds’ gains a different meaning, it grasp the origins of sound when ancient sunlight turns into a current perception.
