antenna is particularly sensitive to magnetic fields and outputs a voltage proportional to that field. Monitoring this activity allows us to experience the local fields, and it generates a sitespecific and dynamic aural landscape. Fractal mathematics and research into fractal antennas has focused on reducing the overall size and space an antenna needs to occupy. Joyce Hinterding is interested in the frequency range at the lower regions of the spectrum, where the wavelength is large; her interpretation of recent antenna design research has led her to explore the possibilities for drawing antennas that can receive large wavelengths, on something the size of a standard piece of fine art paper. The lack of any sealant on the graphite leaves the drawings slightly materially unstable, and they function to some degree like open-circuit devices. The result is that, when the drawings are touched, the volume of the sound increases. This change in volume reflects the changes in the electrical conductance of people’s skin, described as the galvanic skin response (GSR). Accordingly, different people have mildly different effects on the drawings when they touch or come into close proximity to them. Joyce Hinterding produces works that explore physical and virtual dynamics. Her practice is based on investigations into energetic forces, through custom-built field recording and monitoring technologies.
