One of Canada's great contributions to the world of cinema is Imax. One of the country's greatest museums, the Ontario Science Centre came together with Imax for the first time in the Omnimax Cinema.
An acoustical disaster waiting to happen.
The room was basically a cylinder covered by a dome. Both of which are focusing elements. To figure things out we obviously resorted to mathematics but we also employed an older tradition - physical scale modeling. Something that, acoustically, works much better than mathematics. To determine the volume of the anticipated room, we filled the model with rice. Which proved much more accurate than our calculations.
Everyone loves the Omnimax Cinema. It is the highlight of a visit to a wonderful museum.
