Raviv Ganchrow - Long Wave Synthesis
Long Wave Synthesis
is a land-art scale sound installation that investigates infrasound, and probes the relations between how we perceive the landscape and long-wave vibrations. The piece creates a complex topography of acoustic waves in a range of 4 to 30 Hz (mostly in the infrasound range, below the threshold of human hearing) spreading out from an array of custom-built, very low frequency generators. Long Wave Synthesis
focuses on material properties of sound, and investigates ways in which a location manifests itself through interactions between walking, territory and sonic attention. The long waves physically interact with the topography and atmospheric conditions, while simultaneously ‘oscillating’ our sense of the surroundings.
The first prototype was presented
on 12 October 2014 at Høybuktmoen near Kirkenes. Raviv Ganchrow’s talk on Long Wave Synthesis
in The Geologic Imagination
(2015). At the presentation of the book on 17 January 2015 at De Balie in Amsterdam, Arie Altena interviewed Raviv Ganchrow about his work. The video of that interview is online
. A second installment
of Long Wave Synthesis
took place as part of the Sonic Acts festival 2015, on 1 March, at a site in the Australië harbour of Amsterdam. It was accompanied by three lectures on infrasound, by Jon Hagstrum, Raviv Ganchrow, and Hillel Schwartz.
