Abstract
A simple wood frame test house was constructed at Ottawa Airport and aircraft noises were recorded at locations in each of two test rooms and outdoors. The construction of the test house was systematically varied by changing interior surfaces and by adding windows. For some tests interior masking walls were added to limit propagation to predominantly through one of the exterior walls of each room. The measured octave band noise reductions were compared to predicted values from laboratory tests of exactly the same constructions. Ground reflections and internal flanking paths were found to influence results. When these were taken into account the mean prediction error was 3.1 dBA for walls without windows and only 0.5 dBA for walls with windows. The remaining errors were mostly due to differences in low frequency resonances between the laboratory and the field situations.

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
