To validate self-reported hearing-related symptoms among personnel exposed to moderately high occupational noise levels at an obstetrics clinic.
Sensitivity, specificity, and predictive values were calculated for questionnaire items assessing hearing loss, tinnitus, sound sensitivity, poor hearing, difficulty perceiving speech, and sound-induced auditory fatigue. Hearing disorder was diagnosed by pure-tone audiometry, distortion product otoacoustic emissions, and HINT (Hearing In Noise Test).
Fifty-five female obstetrics personnel aged 22-63 participated; including 26 subjects reporting hearing loss, poor hearing, tinnitus, or sound sensitivity, and 29 randomly selected subjects who did not report these symptoms.
The questionnaire item assessing sound-induced auditory fatigue had the best combination of sensitivity ≥85% (95% CIs 56 to 100%) and specificity ≥70% (95% CIs 55 to 84%) for hearing disorder diagnosed by audiometry or otoacoustic emission. Of those reporting sound-induced auditory fatigue 71% were predicted to have disorder diagnosed by otoacoustic emission. Participants reporting any hearing-related symptom had slightly worse measured hearing.
We suggest including sound-induced auditory fatigue in questionnaires for identification of hearing disorder among healthcare personnel, though larger studies are warranted for precise estimates of diagnostic performance. Also, more specific and accurate hearing tests are needed to diagnose mild hearing disorder.
验证产科诊所中暴露于中度高职业噪声水平的人员自我报告的听力相关症状。
计算评估听力损失、耳鸣、声音敏感度、听力差、言语感知困难和声音诱发听觉疲劳的问卷项目的敏感性、特异性和预测值。通过纯音听力测定、畸变产物耳声发射和HINT（噪声中的听力测试）诊断听力障碍。
55名年龄在22 - 63岁之间的女性产科人员参与；包括26名报告有听力损失、听力差、耳鸣或声音敏感度的受试者，以及29名随机选择的未报告这些症状的受试者。
对于通过听力测定或耳声发射诊断的听力障碍，评估声音诱发听觉疲劳的问卷项目具有最佳的敏感性≥85%（95%置信区间56至100%）和特异性≥70%（95%置信区间55至84%）的组合。报告有声音诱发听觉疲劳的受试者中，71%预计通过耳声发射诊断为听力障碍。报告任何听力相关症状的参与者测量的听力略差。
我们建议在问卷中纳入声音诱发听觉疲劳，以识别医护人员中的听力障碍，不过需要更大规模的研究来精确估计诊断性能。此外，需要更具体和准确的听力测试来诊断轻度听力障碍。
