Abstract
The Canadian ANSI standard S12.68-2007 method has been developed as a method of estimating effective A-weighted sound pressure levels after wearing hearing protective devices (HPD). The two percentile values would represent the sound attenuation that most individually trained users to achieve or exceed and that a few motivated proficient users to achieve or exceed. The Canadian workplaces of the NOISH 100 spectrum is used and a comprehensive analysis is conducted by Berger and Gauger. A field validation of Canadian workplace is required and would consist in the statistical comparison of field attenuation data. The developments of ANSI standard S12.68-2007 method provides 3 different practical tools to estimate from laboratory data the attenuation that user achieve in the field. The use and reference of ANSI standard S12.68-2007 method by the Canadian standards could be considered, after successful conduction of validation.

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
