An eardrum impedance simulator for use with physical replicas of the human ear canal.
Bibliographic record
Abstract
An eardrum impedance simulator has been incorporated into life-size replicas of the human ear canal. The simulator branches off from the ear canal at the center of the nominal eardrum position. It has been designed so that sound pressure distributions in an ear canal will have the same standing wave ratios as those measured previously in human subjects over the 4–10-kHz range. The key component of the eardrum simulator is a micro-perforated plate, whose holes provide damping through viscous and thermal boundary layer losses. The optimum design specifies 109 holes of 0.06 mm diameter in 0.003-in. shim stock. Measurements of sound pressure distribution in replica ear canals are underway to evaluate the acoustical performance of the eardrum simulator. The sound field is generated by an occluding hearing aid test fixture.

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.
