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 。
