[part of the
Senses of maps series]
These cool arty
sound sculpture's weren't intentionally created as maps per se, but I reckon they do a good job at visualising the physical phenomenon of acoustics, such as; direction, pitch and volume - so in my book, they're maps.
If you're keen to actually
hear some audible maps try out some of these
Soundscape links. I really like these maps - you find yourself transported to a different place, immersed in a different life.
Its not all airy fairy musings though this sound mapping buzz, these maps have definitly got real world benefits. The company
Planete Acoustique, for example, provide a comprehensive range of sound mapping services (until today, more than I had ever really considered existed)
