ISO 12354-1:2017规定了设计用于估算建筑物相邻房间之间空气声隔声的计算模型，主要使用测量数据（表征参与建筑构件的直接或间接侧翼传输）以及结构构件中声音传播的理论推导方法。 描述了一个详细的模型，用于根据ISO 717-1在1/3倍频程100 Hz至3 150 Hz的频带内进行计算，如果元件数据和连接数据可用，可能会扩展到1/3倍频程50 Hz（见附录I）； 可根据计算结果确定单个数字额定值。由此推导出一个适用范围有限的简化模型，使用元件的单数额定值直接计算单数额定值；提出了一种确定简化模型不确定性的方法（见附录K）。 ISO 12354-1:2017描述了计算方案的原理，列出了相关数量，并定义了其应用和限制。

ISO 12354-1:2017 specifies calculation models designed to estimate the airborne sound insulation between adjacent rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements, and theoretically-derived methods of sound propagation in structural elements. A detailed model is described for calculation in frequency bands, in the frequency range 1/3 octave 100 Hz to 3 150 Hz in accordance with ISO 717？1, possibly extended down to 1/3 octave 50 Hz if element data and junction data are available (see Annex I); the single number rating can be determined from the calculation results. A simplified model with a restricted field of application is deduced from this, calculating directly the single number rating, using the single number ratings of the elements; a method to determine uncertainty is proposed for the simplified model (see Annex K). ISO 12354-1:2017 describes the principles of the calculation scheme, lists the relevant quantities and defines its applications and restrictions.
