Each custom built module consists of an electroluminescent light wire linked to a piezoelectric sensor and a microcontroller.
Through its modular setup it can easily be adapted to various urban spaces.
The sensors are used to measure vibrations of architectural solids in a range of low frequencies. These oscillations are triggered by surrounding ambient noise, for example traffic noise.
The sensor data controls the light wires, which are tensed to a spatial net structure. According to the values of the measurement light flashes are generated.
With increasing vibrations the time between flashes becomes shorter and shorter. The stability of this nervous system gets to an end where it collapses and restarts again.
A dynamic light space is thereby created, which creates a visual feedback of the aural activity around the installation.
Silence is gone from today’s urban spaces. Noise pollution is produced, 24 hours a day, 7 days a week. We can close our eyes, but our ears are always open. Unnatural sound disrupts the activity and balance of human or animal life.
Noise in a range of low frequencies is imperceptible by our ears, but is sensed by the whole body. This unheard sound becomes part of our everyday life.
