Haunting Alien Sounds From The Outer Atmosphere
20 Hz probes the limits of perception in a visualization of sound directly from space.
Semiconductor 20 Hz explores the invisible realm of modern science in a hauntingly beautiful visualization of a geo-magnetic storm in the Earth’s atmosphere. Commissioned for the Invisible Fields Exhibition in Barcelona and created with support from the British Council, Ruth Jarman and Joe Gerhardt’s work emits strangely organic chirps and calls from pure solar radiation.
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.
