    针对国内建筑声学工程咨询中通用ISO10140(GB/T19889)与ASTM E90两类标准隔声测试结果作数值比较问题作讨论，从测试原理和环境条件上进行类比，而后通过典型材料的实测数据分别以计权隔声量与传声等级之间进行计算分析后产生的差异性。

    Differences between ISO 10140(or GB/T 19889) and ASTM E90 were discussed in this paper in order to confirm if the weighting result are similar or comparable. Testing data of the certain sample from different lab were also comparison and analysis.
