开发瑞典职业噪声的工作暴露矩阵 (JEM) 并评估其有效性。JEM 由一组经验丰富的职业卫生学家开发，包含 321 个工作类别，包含 1970 年至 2004 年的职业噪声信息。职业噪声信息来自从不同来源收集的测量结果。该时间段标签从 1970 年开始采用 5 年制。每 5 年时间段的估计平均 8 小时 (TWA) 噪声水平（以分贝 [dB(A)] 为单位）编码为 < 75 dB(A)、7584 dB(A) 或 85 dB(A)，并评估峰值水平暴露的风险。使用基于分类共识的斯文森非参数方法对 JEM 的有效性进行了测试，该方法由第二组职业卫生员达成。验证结果显示，在两组不同的职业卫生员之间，对职业噪声暴露进行分类，在分类上有 80% 的一致性，并且没有系统性差异。然而，峰值水平暴露的分类确实显示出相对位置的系统差异。结果将为 JEM 提供更多的权力，因为它可以对 19702004 年瑞典不同工作类别的职业噪音水平进行良好的总体估计。因此，我们打算将其用于进一步的研究，并将其提供给合作者。
To develop a job-exposure matrix (JEM) for occupational noise in Sweden and to estimate its validity.The JEM, developed by a group of experienced occupational hygienists, contains 321 job families with information regarding occupational noise from 1970 to 2004. The occupational noise information derives from measurements collected from different sources. The time period label has a 5-year scale starting in 1970. The estimated average 8h (TWA) noise level in decibel [dB(A)] for every 5-year period was coded either as < 75 dB(A), 7584 dB(A), or 85 dB(A) and the risk of peak level exposure assessed. The validity of the JEM is tested, using Svenssons non-parametric methods based on classification consensus, reached by a second group of occupational hygienists.Validation results show similar to 80% agreement and no systematic differences, in classification, between the two different groups of occupational hygienists, classifying the occupational noise exposure. However, classification of peak level exposure did show a systematic difference in relative position. The results will give more power to the JEM that it gives a good general estimate for the occupational noise levels in Sweden for different job families during 19702004. We, thus, intend to use it in further studies and also make it available to collaborators.
