本文件规定了一种实验室方法，用于测量建筑产品（如墙壁、地板、门、窗、百叶窗、立面构件、立面、玻璃、小型技术构件，如换气装置、通风板（通风板）、室外进气口、电缆管道、运输密封系统和组合）的气载隔声，例如，带有衬里的墙壁或地板、吊顶或浮动地板。 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、边界条件和总损耗系数，根据本文件进行的测量结果不直接适用于现场情况。

This document specifies a laboratory method for measuring the airborne sound insulation of building products, such as walls, floors, doors, windows, shutters, fa？ade elements, fa？ades, glazing, small technical elements, for instance transfer air devices, airing panels (ventilation panels), outdoor air intakes, electrical raceways, transit sealing systems and combinations, for example walls or floors with linings, suspended ceilings or floating floors. 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 total loss factor.
