An acoustical study of IPOD use by university students in quiet and noisy situations
Bibliographic record
Abstract
An acoustical study was conducted for IPod use by university students in quite and noisy situations to determine what actual decibel levels young people choose while listening to their devices, how much they change the volume settings and whether typical use of these portable audio devices may pose an actual risk to hearing health. Two samples of music were used, one from the Hip Hop segment had more low-frequency content and another from the Electronica segment which had more high-frequency content. All testing was conducted in an IAC double-walled sound-attenuating booth. The delivery of sound was controlled using a TDT System III. Music was presented to all listeners from the same black 30 GB iPod Video, with standard earbuds. The maximum output level that any individual listened to was 105 dBA which could pose a risk if listening time were not limited. Health education should target individuals who are at risk so that they learn how to use their portable audio devices more safely.

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.
