The sound artist, Christina Kubisch, is one good example of someone interested in "making the invisible visible" (Infrastructure Tourism). While she may be encouraging us to probe the urban landscape as does reductive science, there is also the intention for the listener to be more aware and present in their environment. The sound work, "Electical Walks" involves listening through wireleess headphones that can respond to electromagnegtic waves in the environment and make them audible. In a sense, this sort of extray hearing is an experiment with the idea of connecting otherwise separate systems and suggesting a physicality to everyday unnoticed apparatus/objects around us.
