O som no ar

Materials: plexiglass, paper, HD projector, media player

O som no ar [The Sound in the Air] is an abstract attempt to visualize bats’ sonar sounds. In the video the rodents’ [chiroptera] echolocation sounds are represented by a network of metal cables. These form an irregular drawing which maps the surface of the acrylic screen, while also being reflected throughout the exhibition space. Inside of the acrylic structure there is a sheet of paper which absorbs the projected lines of the video, as if retaining the trace or memory of the mapping process.
