"Ekko" creates an interactive sound environment in Hjallerup through wooden frame structures housing computer-controlled audio. The geometric frames position speakers at calculated locations, creating spatial sound distribution. Visitor movement triggers audio responses-sensors detect position and movement, adjusting sound output accordingly. The wooden frames define acoustic zones while maintaining visual transparency. Each frame's geometry affects sound propagation: angles reflect audio, openings allow passage, materials absorb or transmit frequencies. Frank's concept links spatial geometry to acoustic experience; Reiner's framework ensures precise speaker positioning for intended sound field. The installation responds to Danish landscape context, wooden construction harmonizing with local architectural traditions.
Research: Speaker positioning follows acoustic geometry principles-distance, angle, and height affect sound field characteristics. The wooden frames create modular acoustic zones, each with specific sound properties. Sensor integration required careful placement for reliable visitor detection without visual intrusion. The computational system maps visitor positions to audio parameters in real-time, creating responsive soundscapes. Frame geometry balances acoustic function against structural requirements for outdoor installation in Danish weather conditions.
