“Today there are various sophisticated methods to locate sound (acoustic camera, methods of acoustic holography, microphone arrays), but known visualizations by spectrograms still strongly remind of thermographic images. acoustic shapes, unlike thermographic ones, differ from the contour of the measured object. image overlays make it even more difficult to read and compare the results. the diploma “digital acoustic cartography” is an interactive experiment in mapping sonic events into a concrete visual language. source material for the visualizations are images and image-sequences recorded by the “acoustic camera” (microphone arrays with camera), developed by the society for the promotion of applied informatics (GFaI) in berlin, germany (http://www.acoustic-camera.com) […]”
