【摘要】 １９９３年８～１２月，我们对某船厂３９个噪声作业岗位，按船舶工业工业性噪声危害程度分级标准（试行草案）进行测试分级，结果是８７．２％噪声岗位评有级别，０级１１．７６％、Ⅰ级５０．００％、Ⅱ级２９．４１％、Ⅲ级５．８８％、Ⅳ级２．９４％。这对工业噪声岗位的科学分级管理具有一定应用价值，并为正式制定其分级标准提供参考建议。更多还原

【Abstract】 According to the noise grading standard(tentative) of ship industrial an investigation was carried out from August to December in 1993 in a shipyard to examine the hazard degree of noises in 39 working spots. The result showed at 34 of the 39 working spots (87.2%) were graded as follows:Grade 0-11. 76%,Grade 1-50. 00%,Grade 2-29. 41%,Grade 3-5. 88% and Grade 4-2. 94% . This indicates that the grading standard is applicable for scientific management of noisy workshops. In addition, this study provides firsthand information for working out permanent grading standard in the future.更多还原
