OBJECTIVE
Determine whether occupational noise exposure increases audiometric asymmetry.
DESIGN
Audiograms were performed on 2044 men from the Occupational Noise and Hearing Survey, representing four groups based on preliminary screening (for previous noise exposure, otologic history, and otoscopy) and current occupational noise exposure. The effects of current noise exposure on audiometric asymmetry were tested using ANCOVA, with binaural average thresholds as covariates.
RESULTS
There were no significant differences in asymmetry attributable to current occupational noise exposure.
RESULTS
Occupational noise exposure does not usually cause or exacerbate audiometric asymmetry.
目的
确定职业性噪声暴露是否会增加听力不对称性。
设计
对职业噪声与听力调查中的2044名男性进行听力图检查，根据初步筛查（既往噪声暴露、耳科病史和耳镜检查）和当前职业性噪声暴露将其分为四组。使用协方差分析（ANCOVA），以双耳平均阈值作为协变量，测试当前噪声暴露对听力不对称性的影响。
结果
当前职业性噪声暴露导致的不对称性无显著差异。
结果
职业性噪声暴露通常不会引起或加剧听力不对称性。
