To analyze the correct use of personal protective equipment (PPE) among noise-exposed workers and its influencing factors, providing reference information for noise intervention efforts. In September 2023, a stratified sampling method was employed. Based on the 2022 gross domestic product (GDP) rankings of cities in Guangdong Province, 21 prefecture-level cities were divided into economically developed and less developed groups. Two cities were randomly selected from each group, and 16 to 17 enterprises were randomly chosen from each city as study sites. Twenty workers were included from each enterprise as study subjects. A total of 1200 questionnaires were distributed and collected, and 1099 were valid, with an effective recovery rate of 91.6%. The correctness of hearing protector usage was evaluated according to the GB/T 23466-2009 "Guidelines for the Selection of Hearing Protectors", and the personal attenuation rating values of the workers' hearing protectors were measured. A self-designed Questionnaire on the Use of Hearing Protectors by Noise-Exposed Workers was used to investigate PPE-related usage. Multivariate logistic regression analysis was conducted to identify factors influencing the correct use of PPE. A total of 429 (39.0%) noise-exposed workers were able to use PPE correctly during work. Multivariate logistic regression analysis showed that age, working hours, gender, occupational noise protection knowledge score, whether PPE was checked after use, and the frequency of peer supervision on PPE usage were significant factors influencing the effective use of PPE (<0.05) . The correct use of PPE by noise-exposed workers still needs to be improved. The level of occupational health education in enterprises should be enhanced to promote the correct use of PPE by noise-exposed workers.
分析噪声暴露工人个人防护用品（PPE）的正确使用情况及其影响因素，为噪声干预工作提供参考信息。2023年9月，采用分层抽样方法。根据广东省2022年城市国内生产总值（GDP）排名，将21个地级市分为经济发达组和欠发达组。每组随机抽取2个城市，每个城市随机选取16至17家企业作为研究地点。每家企业纳入20名工人作为研究对象。共发放问卷1200份，回收1099份，有效回收率为91.6%。根据GB/T 23466-2009《护听器选择指南》评估听力保护器使用的正确性，并测量工人听力保护器的个人衰减额定值。采用自行设计的《噪声暴露工人听力保护器使用情况调查问卷》调查个人防护用品相关使用情况。进行多因素logistic回归分析以确定影响个人防护用品正确使用的因素。共有429名（39.0%）噪声暴露工人在工作期间能够正确使用个人防护用品。多因素logistic回归分析表明，年龄、工作时长、性别、职业噪声防护知识得分、使用后是否检查个人防护用品以及同事对个人防护用品使用的监督频率是影响个人防护用品有效使用的显著因素（<0.05）。噪声暴露工人个人防护用品的正确使用仍需改进。应提高企业职业健康教育水平，以促进噪声暴露工人正确使用个人防护用品。
