Cultivating the space for prayer and peace in a city like Toronto is difficult. The environmental hurdles of the Ismaili Centre site were monumental. Using sophisticated 3D noise modelling and innovative isolation techniques, our team helped bend the environment to the needs of the client. The Prayer Hall is the heart of the Ismaili Centre. Its elegant glass dome rises in the skyline. It was difficult to provide adequate acoustic absorption in a room that is mostly glass. Custom acoustic panels were carefully designed to an exact geometry and size, consisting of vertical wooden slats of varying depth matching the Islamic patterns used throughout the building. These panels were optimized to break-up and absorb the sound waves to distribute the energy and prevent reflection buildup from the surfaces.
