本文件规定了当建筑构件直接受到空气源或结构源激励时，在实验室描述其声辐射特性的测量方法。适用于单叶和双叶元件（见ISO 12354-1:2017附录F，F2）。测量的数量可用作预测方法（如ISO 12354-1和ISO 12354-2）的输入数据，以比较产品或表达要求。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies measurement methods to characterize in the laboratory the acoustic radiation of a building element when it is directly excited by an airborne or structure-borne source. It is applicable to single-leaf and double-leaf elements (see ISO 12354-1:2017 Annex F, F2). The measured quantity can be used as input data for prediction methods, such as ISO 12354-1 and ISO 12354-2, to compare products, or to express a requirement.All current amendments available at time of purchase are included with the purchase of this document.
