标准摘要
[中文适用范围]： 本文件规定了使用在建筑物地板或楼梯上运行的冲击源进行声压测量来确定冲击隔音效果的程序。 这些程序适用于频率范围为 50 Hz 至 5000 Hz 的房间体积为 10 m3 至 250 m3 的房间。 测试结果可用于量化、评估和比较未配备家具或配备家具的房间内的冲击隔音效果，这些房间的声场可能接近或可能不接近扩散场。 [外文原描述]： 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 m 3 to 250 m 3 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.
