前言

GB/T19889《声学建筑和建筑构件隔声测量》分为:

—第1部分:侧向传声受抑制的实验室测试设施要求;

—第2部分:数据精密度的确定、验证和应用;

—第3部分:建筑构件空气声隔声的实验室测量;

—第4部分:房间之间空气声隔声的现场测量;

—第5部分:外墙构件和外墙空气声隔声的现场测量;

—第6部分:楼板撞击声隔声的实验室测量;

—第7部分:楼板撞击声隔声的现场测量;

—第8部分:重质标准楼板覆面层撞击声改善量的实验室测量;

本部分为GB/T19889的第1部分。

本部分等同采用ISO140-1:1997声《学建筑和建筑构件隔声测量第1部分:侧向传声受抑制

的实验室测试设施要求))，以及ISO140-1:1997/Amd1:2004《声学建筑和建筑构件隔声测量第1

部分:侧向传声受抑制的实验室测试设施要求补充件1:对双层轻质板隔墙隔声测试洞口构架的规定

要求))(英文版)。

本部分与ISO140-1:1997相比，存在如下差异:

—本部分删除了ISO140-1:1997的3.1注中及4.1注中考“虑到所推荐的试件安装洞口尺寸，

房间容积取50m，至60m'是合适的”文字这是考虑到小房间内低频扩散场条件难以满足，

并且我国现有的隔声实验室容积一般大于此推荐值。

—本部分将ISO在2004年通过的对ISO140-1:1997的补充文件ISO140-1:1997/Amd1:2004

声《学建筑和建筑构件隔声测量第1部分:侧向传声受抑制的实验室测试设施要求补充

件1:对双层轻质板隔墙隔声测试洞口构架的规定要求》并人，列为附录D,

本部分按国家标准的要求对ISO140-1:1997做了一些编辑性修改

本部分的附录A、附录B和附录D为规范性附录，附录C为资料性附录。

本部分由中国科学院提出。

本部分由全国声学标准化技术委员会((SAC/TC17)归口

本部分起草单位:同济大学、中国建筑科学研究院。
