1995- 1997年，对挪威北特隆德拉格县的成年人进行纯音听力测定。51975名参与者还提供了关于职业和休闲噪音暴露、以前的汽车感染和头部受伤的问卷信息。计算低（250和500 Hz）、中（1和2 kHz）和高频（3、4、6和8 kHz）的双耳平均值。其目的是估计听力损失的程度与不同年龄和性别的不同类型的接触有关。噪音，汽车感染和头部损伤解释了1-6%的听力损失差异（随年龄，性别和频率范围而变化），除了年龄本身可以解释的差异（30-58%）。在女性中只能检测到轻微的噪音影响。根据其他预测因素调整后，44岁以上男性职业噪声的前10%平均有8-9分贝的高频损失。在同一组中，暴露于脉冲噪声（狩猎、运动射击）会导致7-8分贝的高频损失。经常使用个人立体声播放器或经常参加迪斯科舞厅或摇滚音乐会没有明显的影响。反复耳部感染和头部损伤有明显的影响。
Pure-tone audiometry was administered to the adult population in Nord-Trondelag County, Norway, 1995-97. The 51975 participants also provided questionnaire information about occupational and leisure noise exposure, previous car infections, and head injury. Values averaged over both ears were calculated for low (250 and 500 Hz), middle (1 and 2 kHz) and high frequencies (3, 4, 6 and 8 kHz). The aim was to estimate the magnitude of hearing loss associated with various types of exposure by age and sex. Noise, car infections and head injury explained 1-6% of the variance in hearing loss (varying with age, sex, and frequency range), in addition to what could be explained by age alone (30-58%). Only moderate effects of noise could be detected among women. The upper tenth percentile regarding occupational noise among men older than 44 years had on average an 8-9-dB high-frequency loss, adjusted for other predictors. Exposure to impulse noise (hunting, sports shooting) caused a 7-8-dB high-frequency loss in the same group. No significant effects of frequent use of personal stereo players or regular attendance at discotheques or rock concerts could be demonstrated. There were clear effects of recurrent ear infections and head injury.
