Abstract
The Four Seasons Centre for the Performing Arts, 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 auditorium, 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 auditorium from the vibration and noise from the adjacent subway system on University Avenue and surface streetcars on Queen Street. A ‘‘building within a building’’ vibration isolation design was developed that set the entire auditorium, stage, and rehearsal hall on rubber isolation bearings. This paper provides design details and 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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
