声学.空气声和冲击声隔绝及辅助设备声音的现场测量.测量法

[中文适用范围]： 本文件规定了测量 a) 房间之间的空气传播隔音，c) 外墙空气传播隔音，b) 地板冲击隔音，d) 服务设备在房间内产生的声压级的现场调查方法。 本文件中描述的方法适用于住宅房间或类似尺寸（最大 150 m3）的房间的测量。 对于空气隔声、冲击声隔声和立面隔声，该方法给出与（倍频程）频率相关的值。 通过应用 ISO 717-1 和 ISO 717-2，它们可以转换为表征声学性能的单个数字。 对于重/轻冲击隔音，结果也以 A 计权最大冲击声压级给出。 对于服务设备声音，结果直接以 A 或 C 加权声压级给出。 [外文原描述]： 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 m 3 . 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.
