A questionnaire survey on the prevalence of self-reported voice disorders in school teachers, and classroom noise in Japan
Bibliographic record
Abstract
School teachers are known as professional voice users, hence any damage to their voice or throat could compromise their work as well as their lives. We conducted a questionnaire survey of 830 teachers working at elementary schools, junior-high schools, high schools and schools for children with special needs in Saitama prefecture in Japan. We investigated the prevalence of self-reported voice disorders in teachers and how their quality of life might be influenced. We also asked the teachers to share some of their experience with noise in classrooms. We found the following three points. Firstly, more than a quarter have consulted medical doctors for problems with their voice or throat. Secondly, quality of life of female teachers are slightly more affected by their voice problems than their male peers. Thirdly, approximately 20 percent of teachers are concerned about the noise in their classrooms.

How this classification was reachedexpand
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.
