20 Hz



This video by Semiconductor was made for the exhibition Campos invisibles: Geografías de las ondas de radio (Invisible fields: Geographies of radio waves), which right now is at Arts Santa Monica in Barcelona (the city where I live).
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.
Semiconductor are Ruth Jarman and Joe Gerhardt, an artist duo who explore the material nature of our world and how we experience it, questioning our place in the physical universe.
