I had the opportunity to work for a few days with Andrew Pelling from the Laboratory of Biophysical Manipulation at the University of Ottawa. We came up with an experiment for the interaction of living cells with local pressure waves. Although we didn't arrive at any experimental outcomes, the effects of infrasonic frequencies in water were quite compelling. The frequencies are produced by a Pd oscillator and visualized through a projector when light is reflected off the waters undulating surface. The result was, Darkfield a collaborative experiment on a way to affect the growth patterns of cell colonies with infrasonic architectures. Some of the waveforms that the team has uncovered are projected live in the installation space. These waveforms can be disrupted by their experimental field conditions through sonic input from participants. This work considers the dynamic influence of sound on living organisms in our surroundings.
