The Application of Transfer Matrix Method in Acoustic Performance Analysis of Composite Materials and Acoustic Protection Design of Ship

[摘要] This research introduced the transfer matrix method to calculate the acoustic performance of composite materials, which solving the problem of traditional methods existing in calculating acoustic performance of complex composite structure. Based on the impedance tube method and the reverberation chamber method, the experiment of measuring sound absorption and insulation parameters of typical composite materials was conducted. And then, the validity of theoretical calculation of the transfer matrix method was verified. In addition, under the application of the statistical energy method, the model simulation was carried out by taking a ship as an example, and the transfer matrix method in the noise protection design of the ship was discussed.
