SUPPORTING BETTER NOISE CONTROL IN CANADIAN BUILDINGS
Bibliographic record
Abstract
A simplistic requirement for minimum STC of the wall or floor/ceiling assembly separating adjacent units in multi-family residential buildings has been used in North American building codes for over 50 years. Effective noise control requires replacing the traditional design objective with a requirement including the effect of flanking transmission, such as the Apparent Sound Transmission Class (ASTC). Such a transition requires a supporting set of technical standards for measuring direct and flanking sound transmission for typical assemblies and junctions, plus a credible procedure for calculating system performance from these inputs. Implementing a new approach in practice also needs technical support including calculation tools suitable for both the design and regulatory communities, and data on performance of typical generic constructions. This paper discusses key projects at the National Research Council of Canada both to establish the technical infrastructure supporting such a change in Canada’s building codes and to provide the tools needed by designers seeking to provide enhanced noise control.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
