KEHAI (invisimobile sonic sense)

Theme. Science tells us that sound is only one part of the vibratory spectrum. A different perception could explain that vibration is only one small part of the possibilities of sound.

Concept. Hearing with your eyes and body, feeling silence with your ears.
: Experiencing a different side of sound.

Entering the large space the observer is not embraced by any recognisable sound, which is the case with most sound installations. Instead the observer/participant is welcomed into the, apparent silent, space to explore the source of the unusual feeling that overcomes apon entry. Eyes and bodies are drawn to the floating entities. Ears are pressure gauges measuring the atmospheric differences.

Multiple helium filled balloons, of varying sizes, roam the space and act as sonic concavic lens’ through which the inaudible is transformed into the sensory. The unique property of helium facilitates the balloons in being a receiver of sub-harmonic sound, transforming it and then transmitting it out in all directions . Wireless microphones fitted to the balloons/lens’ transmit these frequencies to the receiver connected to balloon (A). Balloon (A), attached to the ceiling via a sub-harmonic monitor, shoots forth the otherwise inaudible sound, in all directions, to be picked up once again by the roaming balloons. Placing an ear close to the balloon, the participant can simeltaniuosly sense the vibration and pressure as well as the silence. The dampness of the hanging material alters the altitude of the balloons. This coupled with the ever-changing position of the lens’ and the unique atmospheric sounds produced by visitors, creates a constantly shifting loop.

Karaphone

fan-band plays the Karaphone

The sound installtion is composed of ordinary electric fans, springs, magnets, and tubes operating harmoniously in random patterns of motion. The fans act as speakers, and their revolutions output an energy converted later into sound. Through a process of electrical conversion using contact microphones, the vibrations caused by the slowly revolving fans are amplified. Using bamboo tubes of varied lengths, a resulting output is reproduced from a single speaker, hidden at the bottom of each tube. Finally, in the corner of the large warehouse space where the piece is installed stands a piece of steel tubing attached to the building itself. Serving as a transducer for capturing sound vibrations coming from outside of the warehouse, the result is sustained presence of natural environmental noise, heard through a metallic filter.
