Objective: To describe personal music player (PMP) usage among adolescents, sociodemographic determinants and association with audiometric notches. Design: Audiometric evaluation to assess hearing status, and standardized questionnaires to evaluate PMP listening behaviors, leisure noise exposures and self-reported hearing loss symptoms. Sociodemographic information was collected using a parent questionnaire. Noise exposure by PMP usage equivalent for a 40h week was estimated based on self-reported volume and duration of use. Study sample: A total of 2143 students (54% females) attending 9th grade in Regensburg, Germany, during 2009 to 2011. Results: Overall, 85% of the students reported using PMPs. Exposure level exceeded 80dB(A) in approximately one third, and 85dB(A) in one quarter, of those who used PMP. An audiometric notch was found in 2.3% of participants, but was not significantly associated with higher PMP exposure. Conclusions: PMP exposure above the occupational limits of 80 and 85dB(A) set by the Directive 2003/10/EC may be a risk factor for developing noise-induced hearing loss. Educational measures to ameliorate high risk behaviors in PMP usage are needed, particularly for socially disadvantaged groups.
