Abstract

fetched live from OpenAlex

New digital portable audio devices such as the Apple iPod have caused renewed concerns that recreational noise exposure may pose a danger to the hearing health of young adults. In this study, 150 undergraduates completed a survey about their use of portable audio devices and about other factors that could affect their hearing health. In addition to completing the survey, 24 students also participated in an experimental session. In the experimental session, hearing thresholds up to 14 kHz were measured and objective acoustical measures of output of the iPod were obtained. Participants listened to music and adjusted an iPod to their preferred setting in five conditions: in quiet and in two types of background noise, traffic or multi-talker babble background, at a high and a low level. A Bruel and Kjaer dummy head and PULSE sound analysis system were used to measure the output of the iPod at the preferred settings of the students and at predetermined volume and equalizer control settings. It was found that most students use portable audio devices, but the pattern of their usage seems to be potentially hazardous only for a minority. The importance of education about safe usage of this technology is emphasized.

Full frame distilled prediction

Teacher imitation

Not 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.
