20Hz (2011)Semiconductor  20Hz 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 is UK artist duo Ruth Jarman and Joe Gerhardt.
Through moving image works they explore the material nature of
our world and how we experience it, questioning our place in the
physical universe. Their unique approach has won them many
awards and prestigious fellowships, most recently the Samsung
Art + Prize 2012 for new media, the Golden Gate Award for New
Visions at San Francisco International Film Festival USA 2012
and the Art and Science Award at
