The acoustic activity produced by walking, breathing, sending and receiving messages with a mobile phone, murmuring, laughing, and coughing, was recorded with two condenser microphones. Without any manipulation, this material is played back randomly through a high-resolution digital player installed in the surroundings of the exhibition space.

The recordings are made with professional equipment in optimal conditions to archive the natural acoustic qualities of the sound sources, amplified through studio monitor speakers to keep a realistic nature in the sound source.
