摘　　要：本文简述了空气声隔声原理,从标准对建筑含窗外墙隔声量的要求谈起,阐述了建筑含窗外墙空气声隔声性能的估算方法,分析了含窗外墙总隔声量与窗墙比、建筑外窗隔声量和墙体隔声量之间的关系,重点从目标设定、材料选择、玻璃配置、密封构造和环境噪声预测等方面阐述了提高建筑含窗外墙空气声隔声性能的方法。This paper briefly describes the principle of sound insulation of airborne sound.Starting from the standard requirements for sound insulation of exterior walls with windows,the estimation method of airborne sound insulation performance of exterior walls with windows is expounded,and the total sound insulation of exterior walls with windows is analyzed.The relationship between the window-to-wall ratio,the sound insulation of building exterior windows and the sound insulation of walls,the main influencing factors of the total sound insulation of external walls including windows are analyzed,focusing on target setting,material selection,glass configuration,sealing structure and environmental noise prediction The methods of improving the air-borne sound insulation performance of the exterior walls of buildings with windows are expounded.
