To analyze and correlate the audiometric findings of high frequencies (9-16 kHz) in adolescents with their hearing habits and attitudes, in order to prevent noise-induced hearing loss.
This was a descriptive cross-sectional study, which included 125 adolescents in a sample of normal-hearing students, at a state school. The subjects performed high-frequency audiometry testing and answered a self-administered questionnaire addressing information on sound habits concerning the use of personal stereo devices. The sample was divided according to the exposure characteristics (time, duration, intensity, etc.) and the results were compared with the observed thresholds, through the difference in proportions test, chi-squared, Student's t-test, and ANOVA, all at a significance level of 0.05.
Average high-frequency thresholds were registered below 15 dB HL and no significant correlation was found between high frequency audiometric findings and the degree of exposure.
The prevalence of harmful sound habits due to the use of personal stereo devices is high in the adolescent population, but there was no correlation between exposure to high sound pressure levels through personal stereos and the high-frequency thresholds in this population.
分析青少年高频（9 - 16千赫）听力测定结果与其听力习惯和态度之间的关系，以预防噪声性听力损失。
这是一项描述性横断面研究，纳入了一所公立学校125名听力正常学生样本中的青少年。受试者进行了高频听力测定测试，并回答了一份关于个人立体声设备使用的声音习惯信息的自填问卷。样本根据暴露特征（时间、持续时间、强度等）进行划分，并通过比例差异检验、卡方检验、学生t检验和方差分析，将结果与观察到的阈值进行比较，所有检验的显著性水平均为0.05。
高频平均阈值记录在15 dB HL以下，高频听力测定结果与暴露程度之间未发现显著相关性。
青少年人群中因使用个人立体声设备而导致有害声音习惯的患病率较高，但通过个人立体声设备暴露于高声压水平与该人群的高频阈值之间没有相关性。
