MOIRÉ PATTERNS

A temporary site-specific composition for the Platz der Weltausstellung, originally built for the World EXPO in 2000 in the centre of Hannover, Germany.

The sixteen-channel audio was diffused into head-hight mounted speakers that formed an expansive sound-field of approximately 200.000 square feet.

​

Analogue to a visual moiré-effect, the composition made use of interferences by superposing almost identical basic sonic patterns that varied slightly in temporal or spectral parameters. Participants could explore the emerging psycho-accoustic gestalts in an ever-changing interaction between their local position in the field, the physicality of sound, and the generative qualities of perception.

The composition was selected for constant diffusion in 2013.
