Solid Sound (2010), an interactive sound installation dealing with the phenomena of sound transmission conditioned by air as the medium of transmission. For people who will be living on the Moon in the future, the lack of air will lead to new and unimaginable ways of communication. The installation offers a solution for listening to sound in an airless space: the futuristic prototype of a device called Teethphones allows people to experience sound in vacuum through their bones. Sound on the Moon will be located in the vibrations of objects and matter where the limits of these vibrating objects will also be limits of sound transmission and expansion. Solid Sound changes the experience of perception and communication: sound is materialized through the human body and transforms our hearing organs, completely changing the experience of listening which is crucial for the formation of language and identity - and for understanding the reality of life on Earth.
