Experimental investigation of the influence of a posterior commissural gap on the glottal flow resistance of a larynx model
Bibliographic record
Abstract
The influence of a posterior commissural gap (or chink) on the pulsated glottal flow was investigated using a driven physical model having a converging coronal-planar profile. Instantaneous orifice discharge coefficients of the model were obtained from the time-varying orifice area and the velocity distribution of the pulsated glottal jet measured in the axial plane using a single hot-wire probe. Sound pressures were also measured to characterize the acoustical influence of the minimum flow through the posterior chink on the radiated sound. A cyclic hysteresis of the orifice discharge coefficients was observed, which indicates a pressure head increase and a net energy transfer from the air flow onto the orifice wall. A comparison between the cases with and without the posterior chink showed that the presence of a minimal flow increased the radiated sound pressure amplitude in the frequency range in which human hearing is most sensitive.

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.
