- Two loudspeakers, sound, modular foam acoustic panels
- Dimensions variable
invertone is an experimental installation that is based on the phenomenon that results from the subtraction of inverted sound waves. In the installation room, which is coated with white sound absorbing acoustic foam, a white noise sound is emitted from the two speakers. All over the room the sound is evenly present except at the centre point right in the middle between the speakers. Here the waveforms face themselves directly and thereby (ideally) erase each other totally.
