摘　　要：随着我国城市化进程的发展,城市噪声污染问题日益严重,而外窗是建筑维护结构隔声的薄弱环节。文章简述了建筑外窗的隔声质量定律、共振和吻合效应等基本声学原理,归纳了不同建筑标准对于外窗隔声性能的要求,提出了单层建外窗和双层外窗的声学性能提升技术路径,为建筑隔声窗的选型和设计提供依据。With the development of urbanization process,the problem of urban noise pollution is becoming worse.Window is the weak link of sound insulation of building maintenance structure.In this paper,the basic acoustic principles such as mass law of sound insulation,resonance and coincident effect are described.The requirements of different building standards for sound insulation performance of Windows are summarized.This paper proposes a technical path to improve the acoustic performance of single-layer and double-layer Windows,which provides a basis for the selection and design of building acoustic insulation Windows.
