通过制定评分标准、采用稳健z比分数及依据《工作场所物理因素测量第8部分:噪声》(GBZ/T189.8—2007)规定的公式,对模拟工作场所的非稳态噪声现场测量规范性、测量结果分析评定、等效声级计算评定三个环节相结合的实验室间比对,对68家职业卫生技术服务机构进行非稳态噪声现场测量能力的评估,非稳态噪声现场测量实验室比对合格率为64.7%(44/68)。提示部分职业卫生技术服务机构技术人员对噪声的定义、测量标准和评价标准未能较好地理解及执行,现场测量操作能力和对结果的评价能力及质量均有待提高,需加强相关培训。
The standardization of on-site measurements of unsteady noise simulating workplaces is based on the establishment of scoring criteria, robust z-score scores, and formulas based on “Measurement of physical factors in workplaces: Part 8: Noise” (GBZ / T189.8-2007) , Measurement results analysis and evaluation, the equivalent sound level calculation and evaluation of the three links of the inter-laboratory comparison, 68 occupational health technical service agencies to assess unsteady noise field measurement capabilities, non-steady-state noise field measurement experiment Room pass rate was 64.7% (44/68). It is suggested that the definition, measurement standards and evaluation criteria of some technical personnel of occupational health service agencies are not well understood and implemented. The ability of on-site measurement and evaluation of results and quality needs to be improved. Related training should be strengthened.
