该研究的目的是比较 250-8000 Hz 范围内噪声对听力敏锐度的特定频率影响，以及职业噪声和脉冲噪声之间特定频率阈值漂移模式的差异程度。对包含 51975 名受试者的成人普通人群样本进行了纯音测听，这些受试者还提供了有关噪声暴露和其他危险因素的问卷信息。在六个年龄和性别组的八个频率中分别估计了由终生职业噪声和脉冲噪声（主要是射击）引起的阈值变化。报告的噪音暴露以及观察到的阈值变化在女性中属于中等水平。在暴露于较高 2% 职业噪声的受试者中，双耳的阈值变化平均达到 13 dB（3000 Hz，年龄 65 岁以上），在男性中，通常在 3000-4000 Hz 时最大。在 45-64 岁男性和 65 岁以上男性中，脉冲噪声引起的变化达到约 8 dB。脉冲噪声的影响在 3000-8000 Hz 处最强，并且在此频率范围内变化很小。
The aim of the study was to compare the frequency-specific effects of noise on hearing acuity across the range 250-8000 Hz and the extent to which the patterns of frequency-specific threshold shifts differ between occupational noise and impulse noise. Pure-tone audiometry was administered to an adult general population sample with 51975 subjects who also provided questionnaire information about noise exposure and other risk factors. Threshold shifts induced by life-long occupational noise and impulse noise (mostly shooting) were estimated separately in six age and sex groups for eight frequencies. Reported noise exposure, as well as observed threshold shifts, were moderate among women. Threshold shifts averaged over both ears among subjects in the higher 2% of exposure to occupational noise, reached 13 dB (3000 Hz, age 65 years+) among men and were generally largest at 3000-4000 Hz. The shifts induced by impulse noise reached approximately 8 dB among men 45-64 years and men 65 years+. The effects of impulse noise were strongest at 3000-8000 Hz and varied little within this frequency range.
