Cartography

Digital Acoustic Cartography has attempted to map noise patterns of everyday objects and events - e.g. the closing of a car door. Essentially, the acoustic pattern resulting from an event is turned into a relief model of sound; this is combined with a photographic overlay of the noise maker. The result is a three-dimensional map of the object and its sound.

The process is still experimental and, if nothing else, produces interesting shapes.
