摘　　要：窗体结构通常是各类建筑结构中隔声能力最为薄弱的环节,提高建筑窗体的隔声性能是获得良好建筑隔声的重要保证。基于结构声振响应模型并结合低频噪声评价指标,本文提出了1种综合分析方法,可用于分析窗体各参数对其隔声性能的影响。参数计算结果表明:尺寸、厚度、边界条件等参数都会对窗体的隔声性能产生影响,不同的评价指标也将影响其分析结果,本文所提方法将有助于窗体各参数的优化设计。Window structure is usually the weakest link of sound insulation capability in all kinds of building structures,and improvement of sound insulation performance of building windows provides an important guarantee tbr obtaining good sound insulation of buildings. Based on structural vibroacoustic response model and combining low-frequency noise evaluation index,this paper proposed a comprehensive analysis method that could be used to analyze the effect of various parameters of window on its sound insulation performance. Parameter calculation results showed that： size, thickness, boundary conditions and other parameters would affect sound insulation performance impact of window ,and different evaluation indexes would also affect its analysis results ;the method proposed in this paper wouht help optimal design of parameters of window.
