Conference Room, Ivry-sur-Seine (France)   Description A new conference room designed to meet optimal intelligibility. A strong accent on design: integrated services for video, an innovative lighting setup optimising energy consumption per m².   Constraints The size of the room: 4m x 7m, Intelligibility is difficult to overcome without amplified speech. The ceiling height: 3.5m, creates a large volume which makes intelligibility a real challenge. A glass wall: translates into an acoustically reflective surface that could have a negative bearing on speech intelligibility.   Solutions An Ultima ceiling provides good balance between sound absorption and sound attenuation. 4 Orcal Canopies reduce the scale of the room and, combined with low background noise levels, optimise speech intelligibility conditions.   Not only do the Canopies act as acoustics baffles, but they also improve light reflectance, with the Extra Microperforated finish enhancing lighting efficiency. The convex Canopies were used to support the video projection system, therefore concealing the projector, associated wires and maintaining the clean aesthetic look of the room. An amplified i-ceilings sound panel, integrated in the 600x600 Ultima tile to relay audio from the video projector.
