Development of a simplified axi-symmetric finite element model of the auditory canal occluded by an earplug: Variability of the attenuation as a function of the input parameters
Bibliographic record
Abstract
A common solution to prevent the problem of hearing loss due to noise exposure consists in using hearing protection devices (HPD) like earplugs (EP) or earmuffs. The first step is to implement and to validate the simplified axi-symmetric model and to extend this model for a more realistic boundary condition for the EP. The second step consists in using indirectly the FEM model to perform a global sensitivity analysis and to determine Sobol indices. In real life, the EC is constituted by a complex assembly of skin, soft tissues and bone parts. An innovative alternative is used here to take into account the coupling between the EP and the EC. In the rest of the frequency domain, the variation of the density, the Young modulus, and their interaction influence the attenuation on the whole frequency band.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
