An Experimental Study of Middle-Ear Vibrations in Rats
Bibliographic record
Abstract
Hearing impairment is one of the most common disabilities. Animal models have been shown to be valuable tools in auditory research, including studies of middle-ear mechanics. Rats are potentially very useful for this purpose. They are low in cost, they are genetically similar to humans, and the middle-ear structures are easily approachable. The goal of the present study is to characterize the frequency response of the rat tympanic membrane. A laser Doppler vibrometer was used to measure the vibrations of the tympanic membrane. Measurements were done on two female Sprague Dawley rats. The tympanic membrane was stimulated with 45 pure-tone sine waves between 250 and 8000 Hz in Rat #1 and with a slowly sweeping signal from 200 – 10 000 Hz in Rat #2. Results at the umbo compare well with previous studies. The first measurements of the frequency response of the rat tympanic membrane at points other than the umbo are also presented.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
