THE effect of resilient channels on ceiling flanking transmission paths
Bibliographic record
Abstract
This paper is the fourth of a series of papers that provide an overview of work conducted by NRC in the past years on flanking transmission. NRC-IRC has carried out extensive studies to characterize flanking transmission through various building components and assemblies in the Flanking Facility1. One of the studies is to examine the effect of resilient channels on ceiling flanking paths. The floor-ceiling assembly in apartment buildings separates two different dwellings and the gypsum board ceiling is usually mounted on resilient channels to meet the requirements of the building code. However for row housing, the floor-ceiling assembly separates two rooms of the same dwelling and typically the floor is not sound or fire rated.. In this case, the gypsum board ceiling is often directly attached to the floor joists and ceiling flanking transmission paths between the two side-by-side rooms shown in Figure 1 can reduce the apparent STC significantly. This paper describes the improvement due to the use of resilient channels.

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.
