Ultra Acoustic Emissions are ultra high and short acoustic waves that arise when materials under stress are degrading.
In Waveform a salt vapor corrodes a steel sheet that bends under a load. Acoustic emissions are captured, scaled down and amplified in real time as pitting corrosion progresses. Acoustic bursts from microscopic cracks will pierce the silence and carry visual tension into the acoustic space.
Iron is present as a mineral in stone, as a component of brushed steel and finally as rust in an aesthetic interpretation of a stress test known as a 'buckling'. A stretched moment of instability that will eventually lead to failure.
