目的 分析2021—2024年河南省洛阳市重点行业工作场所噪声监测结果，为制定相关防控措施提供依据。方法 采用判断抽样法，依据《洛阳市工作场所职业病危害因素监测实施方案》进行噪声监测，依据《工作场所有害因素职业接触限值 第2部分：物理因素》（GBZ 2.2—2007）进行评价，采用描述性流行病学方法进行分析。结果 2021—2024年洛阳市共监测重点行业用人单位1 421家，超标435家，超标率为30.61%；监测工作场所点位4 521个，超标1 265个，超标率为27.98%；监测噪声岗位4 383个，超标784个，超标率为17.89%。2021—2024年用人单位超标率分别为44.53%、41.48%、22.08%、20.88%，工作场所超标率分别为40.07%、36.83%、23.45%、18.85%，岗位超标率分别为22.25%、36.07%、12.68%、8.99%，均呈现下降趋势。不同县区、企业规模和行业的用人单位超标率存在差异，其中嵩县、大型企业和采矿业的用人单位超标率较高，分别为56.96%、38.18%、55.16%。结论 2021—2024年洛阳市重点行业噪声监测超标率呈下降趋势，但噪声危害依然存在，需加强对重点县区、企业和行业的监管，推广工程控制措施和防护装备使用，降低劳动者噪声暴露强度并减少其暴露时间，全社会多部门需共同参与，共同守护劳动者身心健康。

Objective To analyze the noise monitoring results of key industry workplaces in Luoyang of Henan Province from 2021 to 2024, and to provide basis for formulating relevant prevention and control measures. Methods Noise monitoring was conducted using judgment sampling method in accordance with the Implementation Plan for Monitoring Occupational Hazard Factors in Workplaces in Luoyang City. The data were evaluated according to Occupational Exposure Limits for Hazardous Factors in Workplaces-Part 2: Physical Factors (GBZ 2.2-2007), and were analyzed using descriptive epidemiological methods. Results From 2021 to 2024, a total of 1 421 employers in key industries were monitored in Luoyang, with 435 exceeding the standard, and the employer exceeding rate was 30.61%. A total of 4 521 workplace sites were monitored, with 1 265 exceeding the standard, indicating a workplace exceeding rate of 27.98%. There were 4 383 noise-exposed positions were monitored, with 784 indicating the standard, and the position exceeding rate was 17.89%. From 2021 to 2024, the employer exceeding rates were 44.53%, 41.48%, 22.08%, and 20.88%, respectively. The workplace exceeding rates were 40.07%, 36.83%, 23.45%, and 18.85%, respectively. The position exceeding rates were 22.25%, 36.07%, 12.68%, and 8.99%, respectively. All showed a downward trend. There were differences in the exceeding rates among employers in different counties/districts, enterprise sizes, and industries. Among them, Song County, large enterprises, and the mining industry had higher employer exceeding rates, which were 56.96%, 38.18%, and 55.16%, respectively. Conclusion From 2021 to 2024, the noise monitoring over-standard rate in key industries in Luoyang showed a downward trend. However, noise hazards still exist. It is necessary to strengthen the supervision of key counties/districts, enterprises, and industries, promote the use of engineering control measures and protective equipment, and reduce both the exposure intensity and time of workers to noise. All sectors of society need to participate in protecting workers’ physical and mental health.
