【摘要】：目的通过实验室间比对分析职业卫生技术服务机构噪声现场测量操作过程中容易出现的问题,量化评估噪声现场测量操作能力。方法采用对模拟工作场所的噪声现场测量操作能力和测量结果进行评定2个环节相结合的比对方法,对广东省56家职业卫生技术服务机构进行噪声测量操作能力的实验室间比对。根据本研究制定的噪声现场测量方案和测量操作能力评分标准开展比对,采用基于四分位数稳健统计技术的z比分数对测量结果进行分析和评价。结果噪声现场测量操作能力比对环节中,56家机构有16家机构技术人员的噪声测量操作完全符合操作规范要求,其余40家机构的技术人员均存在不规范操作,完全正确操作率为28.6%(16/56)。噪声现场测量结果评定环节中,56家机构共报告223个噪声现场测量结果,有19家机构共22个测量结果为有问题或离群结果;根据z比分数进行判断,有8家(占14.3%)机构测量结果不合格。综合上述2个环节的比对结果,56家机构噪声现场测量操作能力比对的合格率为85.7%(48/56),不合格率为14.3%(8/56)。结论开展噪声现场测量操作能力实验室间比对可以客观评价职业卫生技术服务机构噪声测量技术服务能力,有利于提高其技术服务质量。
[Abstract]:Objective to evaluate quantitatively the ability of noise field measurement in occupational health technical service institutions by comparing and analyzing the problems that may arise in the process of noise field measurement. Methods A comparison method was used to evaluate the performance and results of noise field measurement in simulated workplace. Laboratory comparison of noise measurement ability of 56 occupational health technical service institutions in Guangdong Province was carried out. According to the noise field measurement scheme and the evaluation standard of measurement operation ability, the measurement results were analyzed and evaluated by using the z ratio score based on the quadrant robust statistical technique. Results the noise measurement operation of 16 technicians in 56 institutions was in accordance with the standard of operation, and the technical staff of the other 40 institutions had nonstandard operation, and the correct operation rate was 28.6% (16 / 56). In the evaluation of noise field measurement results, there are 223 noise field measurement results reported by 56 institutions, and 22 results of 19 institutions are faulty or outliers, which can be judged according to z ratio score. There were 8 institutions (14.3%) whose results were not up to standard. According to the comparison results of the above two links, the qualified rate and non-conformity rate of noise field measurement and operation ability of 56 institutions are 85.7% (48 / 56) and 14.3% (8 / 56) respectively. Conclusion the ability of noise measurement can be evaluated objectively and the quality of technical service can be improved.
