中文摘要
背景： 本研究调查了泰国制冰厂工人的工作场所噪声暴露、听力状况、与高频听力损失（HFHL）相关的因素以及职业听力风险。
方法： 一项横断面研究纳入了巴吞他尼府七家制冰厂的137名工人。使用8小时等效连续声压级（LAeq,8h）测量主要生产区域的工作场所噪声水平。在避免工作场所噪声至少14小时后进行纯音测听。HFHL定义为3、4和6 kHz双耳平均听阈>25 dB听力损失。使用逻辑回归识别相关因素。
结果： 工作场所噪声水平范围为82至92 dB(A)，59.1%暴露于≥85 dB(A)。HFHL患病率为30.7%。年龄较大、当前吸烟和工作场所噪声暴露≥85 dB(A)与HFHL独立相关。
结论： 基于控制层级采取的预防措施可能有助于降低制冰厂的职业听力风险。
英文摘要
This study investigated workplace noise exposure, hearing status, factors associated with high-frequency hearing loss (HFHL) and occupational hearing risk among ice factory workers in Thailand. A cross-sectional study included 137 workers from seven ice factories in Pathum Thani Province. Workplace noise levels were measured across major production areas using the equivalent continuous sound pressure level over 8 h (LAeq,8h). Pure-tone audiometry was performed after at least 14 h of workplace noise avoidance. HFHL was defined as a binaural average hearing threshold >25 dB hearing loss at 3, 4 and 6 kHz. Logistic regression was used to identify associated factors. Workplace noise levels ranged from 82 to 92 dB(A), with 59.1% exposed to ≥85 dB(A). HFHL prevalence was 30.7%. Older age, current smoking and workplace noise exposure ≥85 dB(A) were independently associated with HFHL. Preventive measures based on the hierarchy of controls may help reduce occupational hearing risks in ice factories.
