Pulse : a sound sculpture
This sculpture was specifically created to house a group of sensors. It holds two pressure sensors, one proximity sensor and a vibration detector. Placing a wrist on a particular part of the sculpture can cause the vibration sensor to react to your pulse, hence the name.
Pulse produces sparse soundscapes suitable for quiet indoor spaces. Its software can detect when the sensors are being triggered, and in that case reduce the activity of the background sound to give the sensor input more space. Once the sensors become idle it increases the complexity of the background soundscape to compensate.
It was originally displayed at the Martin Bush Gallery, Plymouth, where these images were taken:
The sculptor is Tim Potts.
