Abstract:

Based upon the aircraft noise of Beijing capital international airport，The design of sound insulation window was investigated for noise-sensitive buildings affected by aircraft noise。 One hour equivalent A-weighted sound pressure level LAeq was finally used for the evaluation value of design of sound insulation window，and LAeq was corrected according to person annoyance level associated with the different type of noise and period。The sound insulation values of window that is designed with the corrected LAeq can basically satisfy the requirement of environmental protection 。

摘要：

以北京市首都国际机场飞机噪声为例，对飞机噪声影响区域内敏感建筑物隔声窗的设计进行研究。以1小时等效A声级LAeq作为飞机噪声影响区域内隔声窗设计时飞机噪声的评价量，并依据人对不同类型、不同时间段内噪声烦恼度的不同对LAeq值进行修正。根据修正后的LAeq值设计的隔声窗隔声量基本达到飞机噪声的防护要求。
