本文件规定了测量地板组件冲击隔音的实验室方法。 测试结果可用于比较建筑构件的隔声性能，根据其隔声能力对构件进行分类，帮助设计需要特定声学性能的建筑产品，并评估完整建筑的现场性能。 这些测量是在实验室测试设施中进行的，在这些设施中，通过侧翼路径的声音传输受到抑制。如果不考虑影响隔声的其他因素，如侧翼传输、边界条件和损耗系数，根据本文件进行的测量结果不直接适用于现场情况。 规定了一种使用标准攻丝机（见ISO？10140-5:2021，附件？E）模拟碰撞源的试验方法，如人穿鞋时的脚步声。还规定了使用改进的敲击机或重/软冲击源（见ISO 10140-5:2021，附录F）模拟具有强低频成分的冲击源的替代试验方法，如人的脚步声（赤脚）或儿童跳跃。 本文件适用于具有所有类型地板覆盖物的所有类型地板（无论是重型还是轻型）。 试验方法仅适用于实验室测量。

This document specifies laboratory methods for measuring the impact sound insulation of floor assemblies. The test results can be used to compare the sound insulation properties of building elements, classify elements according to their sound insulation capabilities, help design building products which require certain acoustic properties and estimate the in situ performance in complete buildings. The measurements are performed in laboratory test facilities in which sound transmission via flanking paths is suppressed. The results of measurements made in accordance with this document are not applicable directly to the field situation without accounting for other factors affecting sound insulation, such as flanking transmission, boundary conditions, and loss factor. A test method is specified that uses the standard tapping machine (see ISO？10140-5:2021, Annex？E) to simulate impact sources like human footsteps when a person is wearing shoes. Alternative test methods, using a modified tapping machine or a heavy/soft impact source (see ISO？10140-5:2021, Annex？F) to simulate impact sources with strong low frequency components, such as human footsteps (bare feet) or children jumping, are also specified. This document is applicable to all types of floors (whether heavyweight or lightweight) with all types of floor coverings. The test methods apply only to laboratory measurements.
