OBJECTIVE
To assess the test-retest variability of hearing thresholds obtained with an innovative, mobile wireless automated hearing-test system (WAHTS) with enhanced sound attenuation to test industrial workers at a worksite as compared to standardised automated hearing thresholds obtained in a mobile trailer sound booth.
DESIGN
A within-subject repeated-measures design was used to compare air-conducted threshold tests (500-8000 Hz) measured with the WAHTS in six workplace locations, and a third test using computer-controlled audiometry obtained in a mobile trailer sound booth. Ambient noise levels were measured in all test environments.
STUDY SAMPLE
Twenty workers served as listeners and 20 workers served as operators.
RESULTS
On average, the WAHTS resulted in equivalent thresholds as the mobile trailer audiometry at 1000, 2000, 3000 and 8000 Hz and thresholds were within ±5 dB at 500, 4000 and 6000 Hz.
CONCLUSIONS
Comparable performance may be obtained with the WAHTS in occupational audiometry and valid thresholds may be obtained in diverse test locations without the use of sound-attenuating enclosures.
目的
评估一种创新的移动无线自动听力测试系统（WAHTS）所获得的听力阈值的重测变异性，该系统具有增强的声音衰减功能，用于在工作现场对产业工人进行测试，并与在移动拖车隔音室内获得的标准化自动听力阈值进行比较。
设计
采用受试者内重复测量设计，比较在六个工作场所使用WAHTS测量的气导阈值测试（500 - 8000赫兹），以及在移动拖车隔音室内使用计算机控制听力测定法进行的第三次测试。在所有测试环境中测量环境噪声水平。
研究样本
20名工人作为受试者，20名工人作为操作人员。
结果
平均而言，WAHTS在1000、2000、3000和8000赫兹时所测得的阈值与移动拖车听力测定法相当，在500、4000和6000赫兹时阈值在±5分贝以内。
结论
在职业听力测定中，WAHTS可能具有可比的性能，并且在不使用隔音罩的情况下，在不同的测试地点也可获得有效的阈值。
