| Abstract: | In order to study the influence of the surface density and thickness of aluminum foam composite plates on the sound insulation, the sound insulation of three different groups of composite foam plates was measured and compared with that of other sound insulation materials. The results show that the sound insulation effect of aluminum foam composite board is better than that of plywood and nomex honeycomb, and the sound insulation effect of aluminum foam composite board increases with the increase of surface density and thickness of aluminum foam composite board. |
