Groundborne Noise and Vibration Control at the Toronto Four Seasons Centre for the Performing Arts

This paper describes how the Four Seasons Center for the Performing Arts (FSCPA), Canada's first purpose-built opera house had its grand opening on June 14, 2006. Occupying an entire block of the financial and theatre district in downtown Toronto (across from the Sheraton Hotel), the facility with its 2,000 seat performance hall, is the new home of the Canadian Opera Company, and the performance venue for the National Ballet of Canada. A major challenge for the project's downtown location was isolating the main performance and rehearsal halls from the vibration and noise of the adjacent subway system on University Avenue and surface streetcars on Queen Street. This paper developed a "building within a building" vibration isolation design that set the entire auditorium, stage and rehearsal hall on rubber isolation bearings. Design details are provided along with the procedures used to ensure that the groundborne noise from outside activities would be inaudible. Results of follow-up measurements are presented which confirmed that the vibration design effectively mitigated the outside vibration and noise intrusion inside the auditorium to achieve background noise levels from exterior sources equivalent to the threshold of human hearing.
