Hysteresis, 2025, sound Installation with water, barrel, sub-woofer, hydrophone, recording device, profile light, dimension variable, 10 min loop
Hysteresis was produced using a range of devices including hydrophones, contact microphones and electromagnetic coils to record vibrations and signals around Sihwa Lake. These include the tremors from construction sites, the engines of passing ships, and the electromagnetic emissions from turbines, transmission towers and other human activities. The soundscape, created through field recording, is translated into a cymatic pond where sonic patterns form shifting shapes that reveal hidden resonances and turn them into tactile sensory experiences.
As the hydrophone passes through the mixer, a self-generated feedback loop slowly emerges and activates the resonance of the installation space. This gradual accumulation behaves like a kind of sedimentation and suggests that the space is not a simple surface but a layered environment shaped by continuous echoes of energy and material activity.
