摘要
全国声学标准化技术委员会最近讨论通过了等同采用ISO 140的建筑构件空气声隔声测量的新修订国家标准。文章旨在介绍此标准修订过程中的一些背景材料,有助于该国标(GB/T 19889)的执行和开展这方面的研究工作。
The National Acoustical Standardization Technical Committee had recently approved a new revised national standard （ GB ） for laboratory measurement of airborne sound insulation of small building elements, which is equivalent to the ISO 140. This paper introduces the background information about the revision of this standard and that might be useful for the enforcement and to the related research work.
