HD Video, 4.59 min, b/w, sound
20Hz observes a geo-magnetic storm occurring in the Earth’s upper atmosphere. Working with data collected from the CARISMA radio array and interpreted as audio, we hear tweeting and rumbles caused by incoming solar wind, captured at the frequency of 20 Hertz. Generated directly by the sound, tangible and sculptural forms emerge suggestive of scientific visualisations. As different frequencies interact both visually and aurally, complex patterns emerge to create interference phenomena that probe the limits of our perception. Audio Data courtesy of CARISMA, operated by the University of Alberta, funded by the Canadian Space Agency. Special thanks to Andy Kale. 20Hz is co-commissioned by Arts Santa Monica + Lighthouse. Supported by the British Council. Commissioned for the Invisible Fields Exhibition at Arts Santa Monica, Barcelona. 2011-2012.
Semiconductor is UK artist duo Ruth Jarman and Joe Gerhardt. Over twenty years they have become known for an innovative body of work, which explores the material nature of our world and how we experience it through the lenses of science and technology. They occupy a unique position in the art world, blending, in philosophically compelling ways, experimental moving image techniques, scientific research and digital technologies.
