吻合效应能降低墙体在某些频率范围的隔声性能,而质量定律无法预测其对隔声的影响。为了在理论上预测吻合现象,本文应用统计能量分析理论对单层轻质墙体的隔声进行计算预测,并分别与采用质量定律计算以及实测数据进行对比,结果表明:应用统计能量分析进行隔声计算的方法较为准确可靠和接近实测数据,更为关键的是SEA能预测墙体的吻合效应以及其对隔声性能的影响。因此,可从理论上选择合适的建筑材料和构件以获得舒适声环境。
Anastomosis effect can reduce the sound insulation performance of the wall in some frequency range, but the law of quality can not predict its impact on sound insulation. In order to predict the anastomosis in theory, this paper applies the theory of statistical energy analysis to calculate and predict the sound insulation of single-story lightweight wall, and compares it with the calculated data and the measured data respectively. The results show that the application of statistical energy analysis The acoustic calculation method is more accurate and reliable and close to the measured data. More importantly, SEA can predict the anastomosis effect of the wall and its influence on the sound insulation performance. Therefore, the theory can choose the appropriate building materials and components to obtain a comfortable acoustic environment.
