From now on whenever I hear the term ‘sound sculpture’ the resulting work will be judged in the shadow of Semiconductor duo Ruth Jarman and Joe Gerhardt’s CARISMA radio array visualisation piece 20 Hz.
20Hz observes a geo-magnetic storm occurring in the Earths 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
