The purpose of the article is clear recognizing the expositional value of an interactive sound installation, which inspires combined practices and heterogeneous discourses of citizens. The installation algorithm creates «sound matter» in real time, it allows the visitor to become a co-author, also installation activates different modes of feeling. Our object is the work of art by Andreas Kühne, which created from sounding of buildings, memorials of constructivism. Using the real sounds, the work brings decaying buildings to life, giving them the opportunity to «speak out» and attract the attention of various urban communities.
