In his work “Hear what you see”, Sascha Bachmann makes sound frequencies visible. These are originated by oscilloscopes, Vectra games consoles or modified cathode ray tubes. With Bachmann, the picture of the sound or inversely the sound of the picture is turned into a synesthetic plaything of the idea that our senses, like technology, are capable of translating sounds visually and images acoustically. Try it for yourself. The image-generating sound can be called up via QR code.
