Sound localisation is the ability of a listener to identify the location or source of a detected sound in terms of direction and distance. The human auditory system uses several cues to localise sound sources, including time - and level - differences between the two ears, spectral information, timing analysis, correlation analysis and pattern matching.
Sound locators were used from the middle of the First World War to the early years of the Second World War to passively detect aircraft by picking up the sound of their engines. They became obsolete towards the end of the Second World War with the introduction of radar.

The project is concerned with listening as a creative act in an unpredictable acoustic environment, as an act of cognition that can filter or shape perception by alternately listening to external and internal (embodied) acoustic space, and builds on my ongoing research into hearing aids and sound detection devices.
