Deriving Acceptable Values for Party Wall Sound
Bibliographic record
Abstract
Acceptable values for party wall sound insulation were derived from the grouped subjective ratings obtained from a field survey of 600 subjects and the airborne sound insulation of their 300 party walls. The subjects lived in both row housing and multi-floor apartment buildings in three different Canadian cities and included both owners and renters. The survey results clearly demonstrate that residents are influenced by the amount of sound insulation between them and their neighbour and that the effects are largely independent of the type of housing or type of tenure. Spontaneous responses show increasing negative ratings of their buildings with decreasing sound insulation. Residents with poor sound insulation are more likely to want to move, to be awakened by noises and to have trouble falling asleep due to noises, as well as to think that their neighbours are less considerate. Directly elicited responses are used to determine STC 55 as a realistic goal for acceptable sound insulation and STC 60 as a more ideal goal that would practically eliminate negative effects of neighbour's noises.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
