Tátil/Sonora is an infrasound installation based on tactile transducers and a soundtrack.
The main object, measuring approximately 50x50x50 cm, contains a transducer that allows people to feel an infrasound track that plays continuously by touching or seating on it. The accompanying headphones reproduce an accompanying soundtrack that enables an immersive dialogue in between the ear and the body tactility.
Different versions of the installation have been shown in several spaces, including Galeria Vermelho (São Paulo), Oi Futuro (Rio de Janeiro) and Centro Cultural da Caixa (Rio de Janeiro).
I've haven't added an audio excerpt of the soundtrack because it's rather useless - most of the sound/infrasound information takes is located in the range 12~20 Hz, making it impossible to reproduce with regular speakers/phones and an MP3 file and barely perceptible by human ears.
This installation is part of a research on producing electroacoustic compositions exploring the limits of the audible spectrum and other perceptual possibilities in order to expand the sensory vocabulary of musical expression beyond cochlear sound, and was mentioned as an example of "non-sounding music" by electroacoustic composer Rodolfo Caesar. It also seeks to reproduce part of the bodiliy experience of techno, dub and funk carioca music, with its heavy subsonic basses, in a completely different situation and musical context.
