Quiet Detector is a 2.1m cube, containing 8 hanging LEDs. These turn on in response to sound, picked up by a microphone with adjustable sensitivity. I wanted to explore ways of visualising music in a 3D space, and devised the cube structure early on as a way of isolating an area for experimentation.

The structure responds to sound, but I realised that by turning up the sensitivity of the microphone I could get an inverted response. Because even relatively quiet sounds will produce a response in the LEDs, the piece should encourage people to reduce their noise levels as a way of interacting with it.

The cube can be disassembled and setup in different locations, and the sensitivity of the microphone can be reconfigured to prompt different reactions.

This project could function as an accompaniment to music performance, a noise-pollution detector, or a gallery installation. It began as a music visualisation experiment, but has expanded to engage more generally with the idea of drawing attention to sound and quiet, and making them visible.
