声学建筑和建筑构件隔声测t

第6部分:楼板撞击声隔声的实验室测量

范围

本部分规定了用标准撞击器激励楼板，在楼板下方测量楼板撞击噪声的实验室方法。本方法适用

于对光裸楼板进行测量，也适用于对覆面层的楼板进行测量。

测量结果能够用于比较楼板的撞击声隔声性能，以及根据楼板的撞击声隔声性能对其进行分级

注1:楼板撞击声隔声的现场测量按GB/T19889.7的规定。

注2:重质标准楼板援面层撞击声改善量的实验室测量按ISO140-8的规定。

室内平均声压级soundpressurelevelinaroom

L

声压平方的空间和时间的平均值与基准声压平方之比，取以10为底的对数乘以10，单位:dB。空

间平均是指对整个测试室而言，但不包括声源直接辐射的区域或靠近边界(例如墙面等)的区域，因为它

们对结果会有显著影响。

若使用连续移动的传声器进行测量,L由公式(1)确定:
