Coils of Copper is a site-specific sensory extension for the perception of electromagnetic radiation. The collaboration builds on both Andreas Tegnander’s research into cross-sensory sound installations and Ossip Blits’ previous research on electromagnetic radiation. While our bodies naturally emit low levels of radiation, this radiation is insignificant in comparison to the amount our technological appliances produce. As a result our cities are imperceivable radiation landfills. Through the use of the custom build rotating electromagnetic microphones, this electromagnetic waste is made audible.
