Pulsierende Stille (Pulsating Silence) (2007) – Bernhard Leitner
- walk-through sound-space sculpture
composition 1: tuba multiphonics
composition 2: sound frequencies 74hz and 85hz
- * 1938 in Feldkrich (AT), lives in Vienna (AT)
The two suspended sheets of metal create a passage-like architecture. A loudspeaker chassis is attached to the outside of each one at a precisely determined point. The loudspeakers transmit a beat frequency to the metal. The beat consists of the interference between two frequencies (74 and 85 hz) that lie beneath the human auditory threshold.
The vibration of the metal panels reciprocally affects and defines the enclosed area, transforming the narrow corridor into a softly pulsating acoustic space that not only envelops but also penetrates and pervades the body. Walking through the pulsating interior is a deeply acoustic and sensuous experience, while outside the sculpture stillness reigns.
