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。
目的：通過實驗室間比對分析職業衛生技術服務機構譟聲現場測量操作過程中容易齣現的問題，量化評估譟聲現場測量操作能力。方法採用對模擬工作場所的譟聲現場測量操作能力和測量結果進行評定2箇環節相結閤的比對方法，對廣東省56傢職業衛生技術服務機構進行譟聲測量操作能力的實驗室間比對。根據本研究製定的譟聲現場測量方案和測量操作能力評分標準開展比對，採用基于四分位數穩健統計技術的z比分數對測量結果進行分析和評價。結果譟聲現場測量操作能力比對環節中，56傢機構有16傢機構技術人員的譟聲測量操作完全符閤操作規範要求，其餘40傢機構的技術人員均存在不規範操作，完全正確操作率為28．6％（16／56）。譟聲現場測量結果評定環節中，56傢機構共報告223箇譟聲現場測量結果，有19傢機構共22箇測量結果為有問題或離群結果；根據z比分數進行判斷，有8傢（佔14．3％）機構測量結果不閤格。綜閤上述2箇環節的比對結果，56傢機構譟聲現場測量操作能力比對的閤格率為85．7％（48／56），不閤格率為14．3％（8／56）。結論開展譟聲現場測量操作能力實驗室間比對可以客觀評價職業衛生技術服務機構譟聲測量技術服務能力，有利于提高其技術服務質量。

Objective To analyze the problems easily found in the progress of noise field measurement in occupational hygiene technical service organizations with an inter-laboratory comparison , and to make a quantitative evaluation on their noise measurement operational capacities .Methods Inter-laboratory comparison , a method for evaluating both regular noise field measurement operational capacity and measurement results in the simulated workplaces , was adopted to assess the noise field measurement operational capacity in 56 occupational hygiene technical service organizations in Guangdong province .The regular noise measurement was appraised by measurement schemes and evaluation criteria made in this paper and measure results were analyzed and evaluated by quartile steady technology and z-score method .Results In the comparison process of noise field measurement operational capacity , 16 of all the 56 organizations were qualified and met the technical specification while the rest 40 were unacceptable because of irregular operations during the measure procedure, the total proper operation rate was 28.6%(16/56).In the comparison process of noise field measurement results, among 223 reported results of all 56 organizations, 22 results from 19 organizations were relatively inferior or stray . According to the z-score, the measurement results of 8 organizations (14.3%) were found disqualified.In conclusion, the pass rate of 56 participated organizations was 85.7% (48/56) and the fail rate was 14.3% (8/56) accordingly. Conclusion The inter-laboratory comparison of noise field measurement operational capacity can objectively evaluate the capacity of noise measurement technical service of occupational hygiene technical service organizations , and can help to improve the quality of technical service .
