Deciban (chdh)


Deciban is chdh’s new audiovisual performance where sound and visual shapes emerge from noise. On the screen, a video noise similar to the "snow" of old analog TVs fills the entire space. This hypnotic material, accompanied by its sound alter ego, is animated and set in motion by forces controlled in real time by two performers using laptops.

The noise acquires a structure, a topology, patterns. Shapes emerge, visual and sound movements appear. The public loose himself in the perception of this world full of illusions. In Deciban, phenomena are drowned in a noise universe : noise is information.

Inspired by Claude Shannon’s information theory, Deciban is a research on the perception of digital generated noise that aims to propose a new type of synaesthetic experience.
