We assessed the hearing level, sleep quality, depression status, and life quality of the employees.
The research group contains 380 (56.7%) of 669 employees working in the factory. We used a questionnaire, noise measurement (2016), pure tone audiometry test results of (2015, 2016). SF-12 (short form), mini sleep questionnaire (MSQ), and Beck depression scale.
The employees' mean working period is 13.5 ± 11.9 years. The mean ambient noise level of the factory is 75.5 ± 7.3 dB. We detected hearing loss at 18.6% and 23.2% in 2015 and 2016, respectively. The frequency of hearing loss is 4.7% at the employees working below 85 dB and 27.8% percent at the employees working above 85 dB. Mean working period of the employees with hearing loss (19.7 ± 11.7 years) is higher than mean working period of the employees without hearing loss(13.2 ± 11.8 years) (p < .0.05). The 27.8% of the employees working above 85 dB are used to earmuffs, 44.4% of them sometimes use earmuffs; 38.9% of them are used to earplug; and 44.4% of them sometimes use earplug. Back depression scales showed 31.1% minimal, moderate, or severe depression. The sleep quality of employees working above 85 dB is worse than the others (p < 0.05). SF-12 QoL scores were 39.41 ± 5.59 (physical health) and 36.10 ± 7.76 (mental health). There was not a statistically significant association between scale scores and ambient noise level and hearing level of the workers (p > 0.05).
We suggest the use of personal protective equipment. Working in the noise above 85 dB affected workers' sleep quality to be poorer.
评估员工的听力水平、睡眠质量、抑郁状况和生活质量。
研究组包含在工厂工作的 669 名员工中的 380 名（56.7%）。我们使用了问卷、噪声测量（2016 年）、2015 年和 2016 年纯音测听结果、SF-12（短式）、微型睡眠问卷（MSQ）和贝克抑郁量表。
员工的平均工作年限为 13.5±11.9 年。工厂的平均环境噪声水平为 75.5±7.3dB。我们分别在 2015 年和 2016 年检测到 18.6%和 23.2%的听力损失。在噪声低于 85dB 的员工中，听力损失的频率为 4.7%，而在噪声高于 85dB 的员工中，听力损失的频率为 27.8%。有听力损失的员工的平均工作年限（19.7±11.7 年）高于无听力损失的员工（13.2±11.8 年）（p<.05）。在噪声高于 85dB 的员工中，27.8%的人习惯使用耳塞，44.4%的人有时使用耳塞；38.9%的人习惯使用耳罩，44.4%的人有时使用耳罩。贝克抑郁量表显示，31.1%的人有轻度、中度或重度抑郁。噪声高于 85dB 的员工的睡眠质量较差（p<.05）。SF-12 QoL 评分为 39.41±5.59（身体健康）和 36.10±7.76（心理健康）。量表评分与工人的环境噪声水平和听力水平之间没有统计学显著关联（p>.05）。
我们建议使用个人防护设备。在噪声超过 85dB 的环境中工作会影响工人的睡眠质量。
