Noise levels in adult and pediatric orthopedic cast clinics.
Bibliographic record
Abstract
Prolonged exposure to high-intensity noise has been associated with noise-induced hearing loss, hypertension, psychological stress, and irritability. The National Institute of Occupational Safety and Health considers levels above 85 decibels (dB) as harmful. In the study reported here, we sought to determine whether noise levels in orthopedic cast clinics were within safe limits. A calibrated noise dosimeter was worn by cast technologists during 7 adult and 7 pediatric cast clinics, and noise levels were recorded. Mean equivalent continuous noise levels were 77.8 dB (adult clinics) and 76.5 dB (pediatric clinics), mean noise levels adjusted for an 8-hour day were 76.6 dB (adult) and 75.9 dB (pediatric), and mean peak noise levels were 140.0 dB (adult) and 140.7 dB (pediatric). Mean noise levels in cast clinics were within safe limits and there was no statistical difference in noise levels between adult and pediatric clinics. However, peak noise levels in all clinics exceeded recommended limits, and even brief exposure to noise of this intensity may be hazardous.

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.
