“In 2003,”
Cabinet Magazine tells us, “Berlin-based sound artist Christina Kubisch began an ongoing project called ‘Electrical Walks.’”
For this project, Kubisch has employed “specially built headphones that receive electromagnetic signals from the environment,” transforming those signals “into sound.” In the process, “Kubisch maps a given territory, noting ‘hot spots’ (ATM machines, security systems, electronic cash registers, subway systems, etc.) where the signals are particularly strong or interesting.” In other words, she performs a kind of
audial psychogeography, zones of the city turned into MP3s, “very beautiful, very dense sounds… like a movie, an audio movie.”
The images, represent the sound files those sounds produced, digital noise-maps of urban space.
