Edwin van der Heide, from Holland, is an artist working on the spatial dimension of sounds. In his installations the sounds are visualized or moved from a landscape to another or become a way to explore the surrounding space.
Let’s see some works illustrating the different approaches.
LSP is a performance where image and sound play equally important roles. The performance environment allows the audience to change their perspective continuously. The image is generated by means of a laser projecting on a thin layer of smoke in the space. Image and sound originate from the same real-time generated source in the computer. The development of the performance fluctuates between the dominance of image over sound and vice versa.

Wavescape is translating the the underwater 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 is very perceivable and almost touchable. From the water side you listen in to the underwater space. You hear an incredible depth and width. 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.

Spatial Sounds (100dB at 100km/h) consists of a speaker on a long arm with a counterweight at the other end. The arm can spin, and can be regulated between very slow and very high speeds, with a maximum of 100 km/h. A high-speed distance-measuring sensor is mounted close to the speaker and measures the surrounding space. It scans any objects and visitors in this space. Because it is spinning, it creates a spatial depiction of the space, resulting in a continuously changing, dynamic map, rather similar to traditional radar.
