声学. 建筑和建筑构件的隔声标定. 第2部分: 撞击声隔声

[中文适用范围]： 本文件 a) 定义了建筑物和地板的冲击声隔离的单一数值，c) 定义了根据 ISO 10140 进行的测量结果计算出的地板覆盖物和浮动地板的冲击声降低的单一数值-3和b)给出了根据ISO 10140-3和ISO 16283-2在三分之一倍频程中进行的测量结果以及根据ISO中的该选项在倍频程中进行的测量结果确定这些量的规则16283-2 仅适用于现场测量，d) 规定了评估轻质地板上的地板覆盖物对撞击声压级的加权降低的程序。 本文件中的单数字量旨在评估冲击隔音效果并简化建筑规范中声学要求的制定。 在需要表达不确定性时，会指示以 0.1 dB 为步长的附加单数评估（频谱适应项除外）。 在计算需要时指定单数数量的数值。 附件 A 中给出了扩大频率范围内的测量等级。 附件 B 中给出了根据裸重地板与地板覆盖物的性能获得单数数量的方法。 单数数量的计算示例为附录 C 中给出。 附录 D 中给出了重冲击源和软冲击源（橡胶球）的测量等级。 [外文原描述]： This document a) defines single-number quantities for impact sound insulation in buildings and of floors, b) gives rules for determining these quantities from the results of measurements carried out in one-third-octave bands in accordance with ISO 10140-3 and ISO 16283-2, and in octave bands in accordance with that option in ISO 16283-2 for field measurements only, c) defines single-number quantities for the impact sound reduction of floor coverings and floating floors calculated from the results of measurements carried out in accordance with ISO 10140-3, and d) specifies a procedure for evaluating the weighted reduction in impact sound pressure level by floor coverings on lightweight floors. The single-number quantities in accordance with this document are intended for rating impact sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional single-number evaluation in steps of 0,1 dB is indicated where it is needed for the expression of uncertainty (except for spectrum adaptation terms). Numerical values of the single-number quantities are specified where required for calculations. The rating of measurements over an enlarged frequency range is given in Annex A. A method for obtaining single-number quantities for bare heavy floors according to their performance in combination with floor coverings is given in Annex B. Example calculations of single-number quantities are given in Annex C. The rating of measurements with a heavy and soft impact source (rubber ball) is given in Annex D.
