Case Study
Challenge
A new conference room was designed with an acoustic challenge in mind. The meeting room had to meet excellent levels of intelligibility. Design was critcial and a strong focus was placed on integrating services for the video, implementing an innovative lighting setup and optimising energy consumption per m².

Due to the size of the room (4m x 7m), it was difficult to overcome intelligibility without amplified speech. On top of that, the height of the ceiling at 3.50m created a large volume and a full glass wall partition introduced an acoustically reflective surface that could also have a negative bearing on speech intelligibility.

Solution
These constraints really were a creative challenge! To reach the required intelligibility, an Ultima ceiling was chosen to ensure a good balance between sound absorption and sound attenuation. Four Metal canopies reduced the scale of the room and, combined with low background noise levels, optimised speech intelligibility conditions. Not only do the Metal canopies act as acoustics baffles, but they also provide a large area for light reflectance with the Extra Microperforated surface enhancing lighting efficiency.

The convex canopies were used to support the video projection system, therefore hiding the projector, associated wires and maintaining the clean aesthetics of the room. An amplified sound panel, integrated in the 600 x 600 Ultima tile was installed to relay audio from the video projector.
