Spatial soundsThe installation Spatial Sounds (100dB at 100km/h) by Marnix de Nijs and Edwin van der Heide. Spatial Sounds 100 dB at 100 km/h was set up at Usine-C during the Elektrafestival.

A speaker is mounted on a metallic arm, rotating around at different speeds dependent on the people in the room. Ultrasonic sensors detect the distance to people in the space and changes the sound being played as well as speed of rotation (more technical info here). Sometimes it is moving slowly, but most of the time (probably because there were always quite a lot of people in the space) it is spinning quite fast. A quite simple concept, but it was suprisingly powerful. However, considering the large forces involved, I was mostly thinking about what would happen if the arm broke with all those people around…
