The Acoustic and Cognitive Spaces activity of research and development centers on the reproduction, the analysis/synthesis, and the perception of sound spaces. The team’s scientific disciplines are signal processing and acoustics for the elaboration of spatialized audio reproduction techniques and methods for the analysis/synthesis of a sound field. In parallel, the team devotes a large percentage of its time to cognitive studies on multisensorial integration for a rational development of new sonic mediations based on body/hearing/space interaction.
