Prediction on the Sound Insulation of a Double -Leaf Lightweight Panels

Statistical energy analysis (SEA) is utilized to model sound transmission through a double -leaf lightweight. Calculating the sound insulation by this method and comparing with the measured data have shown that the prediction model may generate a certain difference between the prediction and experimental data, this method, moreover, might further solve the problem of the sound insulation of the complex wall structure by optimizing the configuration of the enclosure structure.
