Study On The Sound Insulation Of Damping Composite Panel And The Effect Of Reinforcement On It

With the negative impact of noise pollution in recent years,more and more people are concerned about it,because the noise will cause damage to people’s hearing,induce a variety of diseases,and interference people’s life and work.Therefore,the research on sound insulation is becoming more and more important,and scholars at home and abroad have also obtained many research results.In this paper,the sound insulation performance of damping composite board is studied,and the connection way of damping composite board is divided into bonding and articulation.The difference between the two connections is that the bonding plate is tightly bonded between the different material plates,and there is no gap;and the hinge composite board has a very thin air layer between the different material plates.In this paper,we will analyze the sound insulation of these two kinds of different connection methods,use MATLAB to compile the program,substitute the parameters of the composite board,calculate the sound insulation of the composite board,compare the two composite board sound insulation performance And use VA One to build the model to verify the rationality of the programming process.In the engineering application,the strength of the damping composite plate will be insufficient,and the reinforcement treatment is generally carried out.Therefore,the influence of the ribs on the sound insulation performance of the damping composite panel is also studied.The sound insulation of the composite plate is not reinforced,which provides some reference for engineering application.
