Scope

本文件描述了用声压测量法测定楼板构件撞击声隔声性能的实验室方法。
测量结果用于楼板撞击声隔声性能的比较和分级,有助于设计具有一定隔声性能的建筑产品,以及估算建筑建成后的现场隔声性能。
本文件的测量在侧向传声受抑制的实验室测试设施中进行,测量结果并不直接适用于现场情况,因为未考虑现场影响隔声的其他因素,如侧向传声、边界条件和损耗因子。
本文件规定了使用标准撞击器(见GB/T 45305.5—2026中附录E)作撞击源的测试方法,标准撞击器模拟穿鞋行走者的脚步撞击。本文件也给出了替代撞击源的测试方法,即使用改装的撞击器或重而软撞击源(见GB/T 45305.5—2026中附录F)来模拟具有强低频成分的撞击,例如来自赤脚行走或儿童跳跃的撞击。
本文件适用于测量所有类型的楼板构件,无论是重质楼板还是轻质楼板以及铺装各类楼板覆面层的楼板均适用。本文件规定的测量方法仅适用于实验室测量。
