ABSTRACT
Background: Noise induced hearing loss is a risk for users of personal compressed music file players.
Materials and methods: A transverse study, cases and non-cases, male and/or female, 6 to 18 years of age, to evaluate the relationship between noise exposure tests and audiometric findings. Subjects with history of ear pathology of different etiology to the objective of the study were excluded. Noise exposure test, audiometry, and impedanciometry were performed. Descriptive statistics were measured, risk measurements were obtained by odds ratio with 95% confidence intervals. Hypothesis tests included chi square test, independent sample ‹ Student’s t- test, and analysis of variance.
Results: 80 subjects were evaluated, 46 (57.5%) male, average age 11.2 years. 51 (63.8%) were users of personal music players, characterized for being older and with higher schooling than non-users.
Conclusions: The applied test was able to discriminate between users and non-users of personal music players and between subjects with and without auditory alterations.
