20Hz by Semiconductor

Semiconductor is artist duo Ruth Jarman and Joe Gerhardt. Through moving image works they explore the material nature of our world and how we experience it, questioning our place in the physical universe. Their unique approach has won them many awards and prestigious fellowships such as the Gulbenkian Galapagos, Smithsonian Artists Research and the NASA Space Sciences. Their work is part of several international public collections and has been exhibited globally including Venice Bienniale, The Royal Academy, Hirshhorn Museum, BBC, ICA and the Exploratorium.

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
