 note = {This paper provides the results of a numerical analysis on the sound transmission to modeled solid and hollow walls in order to investigate an acoustic characteristic of a honeycomb sandwich structure. The Finite Difference Time Domain (FDTD) method is used in this study because it is possible to solve both sound wave propagation in fluid and elastic wave propagation in solid simultaneously. From the results of isotropic solid wall calculations, there is the second transmission wave in the case of thick wall model, which is not observed in the case of thin wall model. On the other hand, the arch-shaped transmission wave is observed in the case of hollow wall model calculation, which is totally different from that of simple solid wall models., 資料番号: AA0063742019, レポート番号: JAXA-SP-07-016},
