Generative multichannel sound installation for resonating surfaces
Manipulating the acoustic feedback (Larsen) effect has a rich history in the music and sound world. Pioneered by the likes of Jimi Hendrix, Steve Reich and others, the natural curve and reaction of the sound to itself exposes an interesting phenomenon rife with musical possibilities. On the other hand, the uncontrollable, wild and often piercing nature of the resulting sound is a headache for sound engineers.
In A Fragile Equilibrium, the phenomenon is explored through physical materials with the use of contact microphones and transducers in a closed loop. The resonant frequencies emanate directly from the surfaces, articulated by manipulations within the feedback loop to create a rich soundscape. This careful balance is easily disturbed by small and unpredictable factors, the harmonics of the room, the vibration of footsteps or even the direct interaction of a curious spectator can disturb the stability of the sound.
Sometimes, only silence remains. The system having exhausted all it’s available energy, it lies in rest, full of potential, waiting for an external push to start again.
This is the second iteration of a fragile equilibrium. The speakers have become unnecessary as the bigger resonating objects provide enough sonic intensity on their own.
