多层玻璃窗隔声效果的数学模型分析

Mathematical Modeling Analysis of the Sound Insulation of the Multi-layer Glass Window

借助物理学声波传播理论,研究单层玻璃隔声的衡量方法,推导出双层窗户比单层窗户隔声效果好的数学模型为I4″/I2=(1-α1)(l-α2)/e2α11,并探讨在有限的建筑材料规定下实现隔声效果最佳的方法.

The paper studies the measure method of mono-layer glass window and deduces the more effective mathematical modelI4″/I2=（1-α1）（l-α2）/e2α11 of double-layer glass window than the double glass window with the help of sound wave propagation in physics.The paper also probes into the most effective way to insult wave under the limited building material.
