Visualising 20 Hz


This video is absolutely brilliant!
Created by UK artists Ruth Jarman and Joe Gerhardt, otherwise known as Semiconductor Films; the hypnotic work visualises 20 hz audio data courtesy of CARISMA, operated but the University of Alberta and funded by the Canadian Space Agency.
They explain their work further stating:
“20 Hz 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.”
