PULSE

Low frequencies sound emissions are produced by elements installed in the exhibition space. Through cinema’s optical sound technique, a small and silent light mill called Crookes radiometer is transformed in a powerful noise generator. The light from a slowly flicking bulb generates mill’s motion which wings alternatively obstruct a laser ray pointed on a photo sensor. Once amplified, the signal is directly transmitted to the architecture through low-frequency transducers shaking the walls
