| 摘 要： | 应用统计能量分析法SEA(Statistical Energy Analysis)预测板隔声量,先建立板材的SEA模型,将板材的隔声量预测转变成求解声振动功率的线性代数方程组,对方程组的变量(SEA参数)值进行确定,得出板材的隔声量,再根据混响室法测量板材实际隔声量。将预测结果与实验结果进行对比分析,证明统计能量分析法能有效的预测板材隔声量。

| Abstract: | Before using statistical energy analysis to calculate the sound transmission loss, establish SEA model first to convert the panel sound transmission loss calculation into the vibration power linearity algebra equation calculation; then calculate the parameter of equation group (SEA parameter) to gain the sound transmission loss of panel; at last, measure the practical transmission loss of panel in a reverberation chamber-noise elimination box. It is testified that statistical energy analysis is an effective method to predict the sound transmission loss of panel after contrasting and analyzing the results of calculation and experimentation. |
