Permafrost is intended to be a soundsculpture addressing in the first place the freezing process of water. At the core of Permafrost is a silent machine producing sounds according to her specific condition: the crystallization process becomes sound source, the outgrowing matter becomes visible and tangible. New possibilities derived from contemporary media are applied as tools. These tools will – hypothetically – uncover new forms of inner perception. With Permafrost Aernoudt Jacobs wants to research the relation between sound and frequencies by investigating how frequencies, not perceivable by the human ear, still can yield sonic processes which will reach the perceptive scope of the listener.
