标准范围

ISO 15712-3:2005规定了一种计算模型，用于估算建筑物立面或其他外表面的隔音或声压级差。该计算基于构成立面的不同构件的降噪指数，包括直接和侧面传输。根据ISO 140-5，计算结果与现场测量结果大致一致。可以对频带或单个数字额定值进行计算。计算结果也可用于计算室内声压级，例如道路交通引起的声压级；该用途在资料性附录D中处理。ISO 15712-3:2005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。该模型基于对住宅的预测经验；它也可用于其他类型的建筑，前提是建筑的尺寸与住宅中的尺寸没有太大差异。

ISO 15712-3:2005 specifies a calculation model to estimate the sound insulation or the sound pressure level difference of a fa？ade or other external surface of a building. The calculation is based on the sound reduction index of the different elements from which the fa？ade is constructed and it includes direct and flanking transmission. The calculation gives results which correspond approximately to the results from field measurements according to ISO 140-5. Calculations can be carried out for frequency bands or for single number ratings.The calculation results can be used also for calculating the indoor sound pressure level due to for instance road traffic; this use is treated in the informative annex D.ISO 15712-3:2005 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.The model is based on experience with predictions for dwellings; it can also be used for other types of buildings provided the dimensions of constructions are not too different from those in dwellings.
