Wavescape is a site-specific sound installation originally conceived for the Wilhelminapier, right next to the Erasmus Bridge, in Rotterdam. Wavescape is translating the underwater sound space into an audible acoustic environment. Twentyfour hydrophones (underwater microphones) are placed over a horizontal line in the water. Each hydrophone is connected to its own speaker. There are twentyfour speakers on the water side. This creates a live reproduction of the underwater sound space. The result has a strong sensation of presence and almost touchable. From the water side you listen in to the underwater space that continues over land. You perceive an incredible depth and width in the sound space. The speed of sound underwater is almost five times faster then the speed of sound through the air. This creates a possibility for interesting interferences between both of them. The installation is based on the principle of recording and reproducing wavefronts. This principle is more extensively used in a World Beyond the Loudspeaker and Impuls #6.
