本文件规定了使用在建筑物地板或楼梯上运行的冲击源测量声压来确定冲击声绝缘的程序。这些程序适用于频率范围为50赫兹至5 000赫兹的10立方米至250立方米的房间容积。测试结果可用于量化、评估和比较未配备家具或家具的房间内的冲击隔音效果，这些房间的声场可能接近也可能不近似于扩散场。

This document specifies procedures to determine the impact sound insulation using sound pressure measurements with an impact source operating on a floor or stairs in a building. These procedures are intended for room volumes in the range from 10 m3 to 250 m3 in the frequency range from 50 Hz to 5 000 Hz. The test results can be used to quantify, assess and compare the impact sound insulation in unfurnished or furnished rooms where the sound field may or may not approximate to a diffuse field.
