Abstract
In this paper, based on the acoustic impedance tube model established by COMSOL, we studied the influence of the boundary conditions on the frequency characteristics of the damping acoustic plate, the effect of the thickness of the damping layer on the single-layer and double-layer sandwich structure damping acoustic plate. Based on the simulation results, two conclusions can be obtained: (1) the damping layer can effectively increase the sound insulation of the sound insulation plate, and when the thickness of the damping layer is 2∼3 times of the bottom plate thickness, the performance-price ratio is the highest; (2) the sound insulation characteristics of the damping sound insulation plate follow the law of mass, and the sound insulation increases with the increase of frequency under the free boundary condition, while under the fixed support boundary condition, the low frequency sound insulation is larger.
