ISO 15712-2:2005规定了设计用于估算建筑物房间之间冲击声隔声的计算模型，主要基于测量数据，这些数据表征了参与建筑构件的直接或间接侧面传输，以及结构构件中声音传播的理论推导方法。详细描述了用于频带计算的模型；根据计算结果，可确定建筑物的单个数量等级。由此推导出一个应用领域受限的简化模型，使用元件的单数额定值直接计算单数额定值。ISO 15712-2:2005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。它面向声学专家，并为建筑施工领域的其他用户提供开发应用文件和工具的框架，同时考虑当地情况。所描述的计算模型使用最通用的工程方法，并与指定建筑构件性能的可测量量有明确的联系。本标准描述了这些计算模型的已知局限性。然而，用户应该知道，也存在其他计算模型，每个模型都有自己的适用性和限制。这些模型基于对住宅的预测经验；它们也可以用于其他类型的建筑，前提是建筑系统和构件尺寸与住宅中的建筑系统和构件尺寸没有太大差异。

ISO 15712-2:2005 specifies calculation models designed to estimate the impact sound insulation between rooms in buildings, primarily on the bases of measured data which characterizes 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; the single number rating of buildings 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.ISO 15712-2:2005 describes the principles of the calculation scheme, lists the relevant quantities and defines its applications and restrictions. It is intended for acoustical experts and provides the framework for the development of application documents and tools for other users in the field of building construction, taking into account local circumstances.The calculation models described use the most general approach for engineering purposes, with a clear link to measurable quantities that specify the performance of building elements. The known limitations of these calculation models are described in this standard. Users should, however, be aware that other calculation models also exist, each with their own applicability and restrictions.The models are based on experience with prediction for dwellings; they could also be used for other types of buildings provided the construction systems and dimensions of elements are not too different from those in dwellings.
