An interactive sound installation in Hjallerup, Denmark: a computer-controlled audio system inside wooden frame structures. Sound and spatial layout are coupled so that visitor position and movement affect what is heard. The geometry of the frames and the placement of speakers and sensors define the acoustic field and the zones of response. The work is site-specific; the layout was designed for the Hjallerup context.

Research:
Speaker and sensor positions were set using the geometry of the wooden frames and the desired acoustic response. The algorithm maps visitor position (from sensors) to sound parameters (spatialization, level, or content) so that movement through the space changes the auditory result.
