1.1 本试验方法包括使用标准化攻丝机对地板-天花板组件的冲击声传输进行实验室测量。假设试样构成了进入位于正下方的接收室的主要声音传输路径，并且该室内存在与扩散声场的良好近似。 1.2 可对所有类型的地板-天花板组件进行测量，包括带有浮动地板或吊顶元件或两者的地板-吊顶组件，以及带有任何类型地板表面或地板覆盖材料的地板-顶棚组件。 1.3 本测试方法规定了报告实验室测试数据的统一程序，即地板传输的标准化三分之一倍频程声压级- 由于攻丝机，天花板组件。 1.4 实验室认证- 本试验方法的实验室认证要求见 附件A2 . 1.5 以国际单位表示的值应视为标准值。本标准不包括其他计量单位。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 通过以下方法确定试样下方房间内的噪声频谱: 5.1.1 地板-天花板组件的尺寸和机械特性，如其结构、表面、安装或边缘约束、刚度或内部阻尼， 5.1.2 下面房间的声学响应， 5.1.3 产生冲击的物体或装置的位置，以及 5.1.4 实际影响本身的性质。 5.2 本试验方法基于使用中规定类型的标准攻丝机 8.1 放置在地板上的特定位置。该机器在测试地板上以均匀的速率产生连续的一系列均匀冲击，并在接收室内产生足够高的宽带声压级，即使在存在背景噪声的情况下，也可以在大多数地板类型下进行测量。 然而，攻丝机本身并不是设计用来模拟任何一种类型的冲击，比如由男性或女性的脚步产生的冲击。 5.3 由于其便携式设计，敲击机无法模拟步行者的重量。因此，由这种脚步声激励引起的结构声音，即地板组件的嘎吱声或隆隆声，不会反映在由该试验方法获得的试验结果得出的单次冲击额定值中。实验室攻丝机试验结果与室内冲击激励典型条件下地板的主观验收之间的相关程度尚不确定。相关性将取决于地板结构的类型和建筑物中冲击激励的性质。 5.4 在为满足本试验方法要求而设计的实验室中，其目的是使房间之间的声音传输的唯一有效路径是通过试样。在通常有许多其他声音路径的建筑中，情况并非如此- 侧翼声传输 因此，使用该测试方法获得的声音额定值与建筑物中的声音隔离没有直接关系；它们代表了现场测试中测量值的上限。 5.5 本试验方法不适用于现场试验。根据测试方法进行现场测试 2007年1月 .

1.1 This test method covers the laboratory measurement of impact sound transmission of floor-ceiling assemblies using a standardized tapping machine. It is assumed that the test specimen constitutes the primary sound transmission path into a receiving room located directly below and that a good approximation to a diffuse sound field exists in this room. 1.2 Measurements may be conducted on floor-ceiling assemblies of all kinds, including those with floating-floor or suspended ceiling elements, or both, and floor-ceiling assemblies surfaced with any type of floor-surfacing or floor-covering materials. 1.3 This test method prescribes a uniform procedure for reporting laboratory test data, that is, the normalized one-third octave band sound pressure levels transmitted by the floor-ceiling assembly due to the tapping machine. 1.4 Laboratory Accreditation— The requirements for accrediting a laboratory for performing this test method are given in Annex A2 . 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The spectrum of the noise in the room below the test specimen is determined by the following: 5.1.1 The size and the mechanical properties of the floor-ceiling assembly, such as its construction, surface, mounting or edge restraints, stiffness, or internal damping, 5.1.2 The acoustical response of the room below, 5.1.3 The placement of the object or device producing the impacts, and 5.1.4 The nature of the actual impact itself. 5.2 This test method is based on the use of a standardized tapping machine of the type specified in 8.1 placed in specific positions on the floor. This machine produces a continuous series of uniform impacts at a uniform rate on a test floor and generates in the receiving room broadband sound pressure levels that are sufficiently high to make measurements possible beneath most floor types even in the presence of background noise. The tapping machine itself, however, is not designed to simulate any one type of impact, such as produced by male or female footsteps. 5.3 Because of its portable design, the tapping machine does not simulate the weight of a human walker. Therefore, the structural sounds, i.e., creaks or booms of a floor assembly caused by such footstep excitation is not reflected in the single number impact rating derived from test results obtained by this test method. The degree of correlation between the results of tapping machine tests in the laboratory and the subjective acceptance of floors under typical conditions of domestic impact excitation is uncertain. The correlation will depend on both the type of floor construction and the nature of the impact excitation in the building. 5.4 In laboratories designed to satisfy the requirements of this test method, the intent is that only significant path for sound transmission between the rooms is through the test specimen. This is not generally the case in buildings where there are often many other paths for sounds— flanking sound transmission . Consequently sound ratings obtained using this test method do not relate directly to sound isolation in buildings; they represent an upper limit to what would be measured in a field test. 5.5 This test method is not intended for field tests. Field tests are performed according to Test Method E1007 .
