Optical wave is about perception of sound, balance, fragility and hesitation - in a system that reacts to the slightest impulse. It work as an acoustic feedback loop, producing an undolatory signal which is suspended between saturation and disappearance.  The perceived frequency depends on the materials used and the acoustic environment (elasticity of the air, size of the room, etc). The sound is present as much by his physics (echo, oscillation, amplitude...) as by its plasticity and presence in space. The viewer can speak into the ceramic receivers triggering a vibration of a long tension spring which is picked up by piezoelectric microphones and transmitted to electroacoustic transducers. These transducers in turn re-diffuse the vibration back to the structure, thus making the spring vibrate again, completing the feedback loop in a system that can destroy himself.
