The Orpheum Theatre seats 2800 people and is the home of the Vancouver Symphony. Renovations carried out by Aercoustics in 1995 addressed several problems including a phenomenon known as image shift. In The Orpheum, singers or soloists appeared to be perched somewhere above the ceiling. Corollaries of this effect meant that it was very difficult for conductors to achieve a reliable balance between the different sections of the orchestra. A 1:48 scale model was used first to confirm the existence of the problem and then to fine tune the solutions. Convex reflectors were hung underneath the offending areas of the ceiling. Other acoustical work included HVAC noise control and the removal of some unnecessary reflectors above the stage. Winner of the 1996 Canadian Consulting Engineers Award of Merit.
