With Hidden Noises – installation: an interactive audio installation based on Marcel Duchamp’s sculpture of the same name. The original sculpture contains an unkown object placed inside by Duchamp’s patron and collector Walter Arensberg. The sculpture rattles when shaken, making it an early example of audio art. Unfortunately, it is usually displayed in a vitrine and patrons aren’t allowed to activate it. Visitors to my installation can handle a replica of Duchamp’s readymade containing electronic sensors instead of an unkown object. Their interactions with the scultpture cause it to produce a variety of sounds related to Duchamp’s work.
