20hz by Semiconductor (video)
This video is amazing! It was created by Semiconductor Films, made up of UK artists Ruth Jarman and Joe Gerhardt and was made for the exhibition Invisible Fields at Arts Santa Monica in Barcelona Spain. The video is a beautiful visualization of sound waves, that are usually not visible. Video after the jump!
“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.”
