Located on a silver slatted structure at the entrance of the Class of 1978 Life Sciences Center, Bill Fontana’s MicroSoundings (figs. 12 and 13) received a similarly positive response. As one approached the building’s entrance, the adjacent structure (originally constructed to control light pollution) came alive with sound: rushing water, low gurgling, or varieties of thumping and hammering. The sound samples themselves, recorded by Fontana from laboratories⁹ and mechanicals inside the building, had a lot of movement, and they played from six speakers arrayed on the interior of the structure. These recorded sounds would alternate with amplified sounds from the ambient environment heard through two additional speakers mounted on a light pole. This ambient sound was captured in real time by two accelerometers attached to the interior of the slatted structure. MicroSoundings painted a sonic portrait of the building made up of the work inside it, the machines that circulated its air and water, and the people and things that vibrated it during daily life.
