标准范围

ISO 140-18:2006规定了人工降雨激发的屋顶、屋顶/天花板系统和天窗冲击隔音的实验室测量方法。所得结果可用于评估降雨对房间或下方空间中给定建筑构件产生的噪声。研究结果还可用于比较建筑构件的降雨隔声能力，并设计具有适当降雨隔声性能的建筑构件。ISO 140-18:2006是基于在受控条件下，在实验室试验设施中使用水箱进行的人工雨滴测量，在该设施中，侧翼声音传输受到抑制。使用真实降雨进行的测量虽然是一种用于验证目的的有用方法，但由于真实降雨的易变性、不可预测性和间歇性，因此不包括在内。目前，研究人员正在研究的其他机械模拟方法还不够成熟，无法从声级和产生的光谱两方面充分模拟真实的降雨。

ISO 140-18:2006 specifies a laboratory method of measurement of the impact sound insulation of roofs, roof/ceiling systems and skylights excited by artificial rainfall. The results obtained can be used for assessing the noise to be produced by rainfall on a given building element in the room or space below. The results can also be used to compare rainfall sound insulation capabilities of building elements and to design building elements with appropriate rainfall sound insulation properties.ISO 140-18:2006 is based on measurements with artificial raindrops under controlled conditions using a water tank in a laboratory test facility in which flanking sound transmission is suppressed. Measurements using real rain, although a useful means for validation purposes, are not included because of the variable, unpredictable and intermittent nature of real rain. Other mechanical simulation methods under investigation by researchers are not sufficiently well developed at present to adequately simulate real rain both in terms of sound levels and spectra generated.
