Cartography

›Digital Acoustic Cartography‹ is an interactive data visualization that transforms sonic events into a readable visual language.

Data Source are image-sequences recorded by the ›Acoustic Camera‹ (Microphone arrays with optical camera), developed by GFaI (Gesellschaft zur Förderung angewandter Informatik) in Berlin, Germany. Both, acoustic and photographic images, are analyzed by a specially developed Software in Processing. The color-spectrum of the acoustic images is used as distortion matrix to warp the source image into a threedimensional relief. The color-spectrum is replaced by the photographic data and and allows to read both optical and acoustic information.

Acoustic Anatomy

›Acoustic Anatomy‹ visualizes the noise-spectrum of different frequencies of automobile gear. The third-octave-bands are clustered between 500 - 5000 Hz in a range of 58 - 74 dB.

Visualization:
Acoustic Kinetics

The kinetic motion of sound of a automobile door strike in 62 ms. For the visualization, 124 individual images with a total of 11,457,600 image pixels were analyzed, processed and imaged.
