This interdisciplinary long-term study examined the effects of recreational noise exposure on the hearing of adolescents. Boys and girls (aged 14-17 years) were examined during a four-year period. Audiological, psychosocial, and sound measurements were performed yearly to determine the hearing threshold level (HTL) of participants in the 250-16000 Hz range, their participation in recreational activities, and the sound levels at discos and through personal music player use. A tendency of the mean HTL to increase in both genders during the study was observed, especially at 14000 Hz and 16000 Hz. Boys had a higher mean HTL than girls. The participation in musical activities increased yearly, 'attendance at discos' being the favourite musical activity for both groups. In general, boys were more exposed to high sound levels than girls. The equivalent sound levels in discos ranged between 104.3 and 112.4 dBA, and between 75 and 105 dBA from personal music players.
这项跨学科长期研究考察了娱乐性噪声暴露对青少年听力的影响。在四年期间对14至17岁的男孩和女孩进行了检查。每年进行听力学、心理社会学和声音测量，以确定参与者在250至16000赫兹范围内的听力阈值水平（HTL）、他们参与娱乐活动的情况，以及迪斯科舞厅和通过个人音乐播放器使用时的声音水平。在研究期间，观察到两性的平均HTL均有上升趋势，尤其是在14000赫兹和16000赫兹处。男孩的平均HTL高于女孩。参与音乐活动的人数逐年增加，“去迪斯科舞厅”是两组最喜欢的音乐活动。总体而言，男孩比女孩接触更高声音水平的机会更多。迪斯科舞厅的等效声级在104.3至112.4分贝A之间，个人音乐播放器的等效声级在75至105分贝A之间。
