Apparent Impact Insulation Class (AIIC) Testing of Various Roof Terrace Assemblies and Evaluating the Need for Additional Mitigation
Bibliographic record
Abstract
Common amenity and private rooftop terraces are common in mid and high-rise condominiums, providing recreational spaces in urban environments. However, there is limited laboratory and field test data available for the impact sound isolation performance of rooftop terrace assemblies, particularly in relation to the absence of requirements related to controlling impact noise in the Ontario Building Code (OBC). This presentation addresses the knowledge gap by conducting field measurements of the transmission of impact sound through various typical rooftop terrace floor/ceiling assemblies. Using the ASTM E1007 test standard, the findings demonstrate that most typical rooftop terrace assemblies have a relatively high AIIC rating, suggesting that they provide sufficient impact sound isolation without any additional mitigation. This research contributes valuable field test data to the existing body of knowledge on impact noise test data on rooftop terrace assemblies and offers insights for acoustical engineers and product development related to noise and vibration.

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.
