Abstract
Many occupational sectors are exposed to noise from very high audible frequencies (VHF) or low-frequency ultrasound (LFUS). Despite numerous studies on VHF/LFUS exposure, the question of the impact of several parameters in the on-site measurement protocol on the representativeness of the measurement remains open. Laboratory measurements were carried out to assess the variability of exposure measurements under controlled conditions as a function of the presence/absence of the microphone’s protection grid, the location of the microphone (shoulder, ear entrance, etc.), the side of the dummy where the microphone is located, and the frequency and angle of the source. Particular attention has been paid to the possibility of positioning the microphone at temple level, thanks to a specific mounting system adapted to on-site use.

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
