20 Hz (by Semiconductor)
Fascinating project. The video gets really good around 3:30
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.
“Above the surface of upwardly sonicated silicone oil, falling droplets of the liquid are suspended by a thin membrane of air, acoustically regenerated underneath each droplet. Without coalescing for extended periods, these palpitating spheroids bounce on the air-oil interface. The repeated impact of a bouncing droplet incites a standing capillary wave that interlocks with the waves of neighboring droplets. This close-range attractive force can result in the orbital motion of droplet pairs and clusters. During more stable modes of excitation, self-organizing geometric rafts emerge in accordance with the closest packing of spheres: the distance between droplets decreases with increasing frequency, leading to dense lattice formation.” Mucilaginous Omniverse.
