Abstract
In 1968, HL Blachford, Inc. constructed their first acoustics laboratory next to their Troy, Michigan plant. This laboratory consisted of a 216-m3 reverberation room with an adjacent large hemianechoic room approximately 12 m long, 5 m wide, and 4.5 m high. After several ownership changes, a plant that used to belong to HL Blachford, Inc. was purchased in 1995 by HL Blachford Ltd. of Canada, and became the new headquarters of a new company called Blachford, Inc. It quickly became obvious that a new laboratory was required for vehicle testing and acoustical material development. The design of a new facility began in 1997 and was based on the old laboratory; however, the new design incorporates design changes to increase the capacity, capabilities, and quality of the facility. The new laboratory is currently under construction and features a larger hemi-anechoic room, approximately 15 m long, 9 m wide, and 6 m high, and a nonadjacent 200-m3 reverberation room with several horizontal and vertical test sections for vehicle component and material testing.

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.
