Transient evoked otoacoustic emissions (TEOAEs) in Caucasian and Chinese young adults
Bibliographic record
Abstract
The goal of this study was to examine the effect of race and gender on transient evoked otoacoustic emission (TEOAE) characteristics. TEOAE amplitude, noise levels, and hearing thresholds were compared in 81 Caucasian (mean age: 27.8 years) and 81 Chinese (mean age: 24.7 years) young adults with normal hearing. TEOAE amplitude was significantly higher in females than males and in the Chinese group than the Caucasian group. Females had better hearing sensitivity than males consistent with TEOAE results. Hearing sensitivity was not statistically different between the two racial groups; however, the interaction between race and hearing thresholds was significant. As the noise levels between the two racial groups were not statistically different, the observed differences are most likely related to differences in middle-ear transmission properties or to differences in cochlear mechanisms. Documentation of gender and racial differences and understanding the underlying mechanism of these differences will not only assist us in understanding how TEOAE will be affected by middle-ear transmission properties but also will help us in establishing normative data in clinical settings.

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.
