Volume is a sound installation which uses its exhibition space as an acoustic object. 24 electronic motors are mounted on different surfaces that are part of the exhibition room – plaster walls, plastic light switches, wooden floorboards, glass windowpanes – with each motor equipped with a small metal spike. When a motor is activated, the spike flicks down and knocks the surface on which it's mounted to produce a specific sound. All the motors are connected to a small main control – an Arduino board and some electronics – which runs a score composed of a series of varying random algorithms. The sounds produced are diverse in temporal and spatial coordination, with each having its own unique origin. The score itself is adapted for every room where the installation is shown.
