ISO 15712-4:2005描述了一种计算模型，该模型主要通过测量建筑物内部的声压级以及表征建筑物外壳中相关元件和开口的声音传输特性的测量数据，来计算建筑物外壳因空气传播声音而辐射的声功率级。这些声功率级与建筑围护结构内部或前方的其他声源的声功率级一起，构成了计算距离建筑物选定距离处的声压级的基础，作为建筑物声学性能的衡量标准。根据室内声源的知识预测室内声压级不在ISO 15712-4:2005的范围内。室外声传播的预测不在ISO 15712-4:2005的范围内。ISO 15712-4:2005描述了计算模型的原理，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。

ISO 15712-4:2005 describes a calculation model for the sound power level radiated by the envelope of a building due to airborne sound inside that building, primarily by means of measured sound pressure levels inside the building and measured data which characterize the sound transmission by the relevant elements and openings in the building envelope. These sound power levels, together with those of other sound sources in or in front of the building envelope, form the basis for the calculation of the sound pressure level at a chosen distance from a building as a measure for the acoustic performance of buildings.The prediction of the inside sound pressure level from knowledge of the indoor sound sources is outside the scope of ISO 15712-4:2005.The prediction of the outdoor sound propagation is outside the scope of ISO 15712-4:2005.ISO 15712-4:2005 describes the principles of the calculation model, 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.
