ISO 10848（所有部分）规定了一个或多个建筑构件侧面传输特性的测量方法。这些测量在实验室测试设施或现场进行。 建筑构件的性能可以表示为构件和交叉口组合的总体数量（例如标准化侧翼声级差和/或标准化侧翼冲击声压级），也可以表示为交叉口的减振指数或交叉口的标准化方向平均振动声级差。 建筑物中的结构声源有两种方法，一种是标准化的侧翼设备声压级，另一种是传输函数，可用于估计接收室内由于结构原因产生的声压级- 源室内的服务设备产生的激励。前一种方法假设侧翼传输仅限于一个连接点（如果支持设备的元件是分离元件，则无连接点），后一种方法考虑直接（如果有）和所有侧翼传输路径的组合。 ISO 10848-1:2017包含测试元件和测试室的定义、一般要求以及测量方法。根据交叉点和涉及的建筑构件类型，给出了选择待测量数量的指南。ISO 10848的其他部分规定了不同类型连接和建筑构件的应用。 表征侧翼变速箱的数量可用于比较不同的产品，或表示要求，或作为预测方法的输入数据，如ISO 12354-1和ISO 12354-2。

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. These measurements are performed in a laboratory test facility or in the field. The performance of the building components is expressed either as an overall quantity for the combination of elements and junction (such as the normalized flanking level difference and/or normalized flanking impact sound pressure level) or as the vibration reduction index of a junction or the normalized direction-average vibration level difference of a junction. Two approaches are used for structure-borne sound sources in buildings, a normalized flanking equipment sound pressure level and a transmission function that can be used to estimate sound pressure levels in a receiving room due to structure-borne excitation by service equipment in a source room. The former approach assumes that flanking transmission is limited to one junction (or no junction if the element supporting the equipment is the separating element), and the latter considers the combination of direct (if any) and all flanking transmission paths. ISO 10848-1:2017 contains definitions, general requirements for test elements and test rooms, and measurement methods. Guidelines are given for the selection of the quantity to be measured, depending on the junction and the types of building elements involved. Other parts of ISO 10848 specify the application for different types of junction and building elements. The quantities characterizing the flanking transmission can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354？1 and ISO 12354？2.
