The Installation SOUNDSPACE at Senckenberg Natural History Museum is based on the comparison of the strategies of the acoustic and visual perception. They searched for the object quality of sound and the discontinuity of the object. The point is to determine the relationship between the immediacy of acoustic, his radical volatility and the resulting absence. The confrontation with this absence opens a kind of double presence: The performed presence of the object and the produced presence of the subject. SOUNDSPACE used the framework of the Senckenberg Museum, with its founding history, from the late 18th to the beginning of the 19th century and its committed idea of Modern Science.
