本文件规定了测量的现场测量方法 a） 房间之间的空气隔声， b） 地板的冲击隔音， c） 立面的空气隔声，以及 d） 由维修设备引起的室内声压级。 本文件中描述的方法适用于住宅房间或类似尺寸房间（最大150 m3）的测量。 对于气载隔声、冲击隔声和立面隔声，该方法给出的值与（倍频程）频率有关。通过应用ISO 717-1和ISO 717-2，可以将它们转换为一个数字，以表征声学性能。对于重/软冲击隔声，结果也作为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 façades, 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 façade 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.
