本文件规定了测量的实地调查方法 a)房间之间的空气隔音， b)地板的冲击隔音， c）fa的空气隔音？ades，以及 d)由服务设备引起的房间内的声压级。 本文件中描述的方法适用于住宅房间或最大150？m3. 对于空气传播隔声、冲击隔声和fa？该方法给出了与（倍频程带）频率相关的值。通过应用ISO 717-1和ISO 717-2，它们可以转换成表征声学性能的单个数字。对于重/软冲击隔音，结果也以A加权最大冲击声压级给出。对于维修设备声音，结果直接以A或C加权声压级给出。

This document specifies field survey methods for measuring a) airborne sound insulation between rooms, b) impact sound insulation of floors, c) airborne sound insulation of fa？ades, and d) sound pressure levels in rooms caused by service equipment. The methods described in this document are applicable for measurements in rooms of dwellings or in rooms of comparable size with a maximum of 150？m³. For airborne sound insulation, impact sound insulation and fa？ade sound insulation the method gives values which are (octave band) frequency dependent. They can be converted into a single number characterising the acoustical performances by application of ISO 717-1 and ISO 717-2. For heavy/soft impact sound insulation, the results also are given as A-weighted maximum impact sound pressure level. For service equipment sound the results are given directly in A - or C -weighted sound pressure levels.
