The vibroacoustic behavior and sound transmission properties of a mock-scale chamber core composite cylinder were studied, and the feasibility of the active structural acoustic control and passive control was also investigated. A box-beam model of the chamber core cylindrical shell was used for calculating the critical frequency and the ring frequency. The coupling problems between structural and acoustic modes were investigated, and the structural and acoustic modal parameters were identified from measured data. The sound transmission into the chamber core cylindrical structure was measured with and without fill materials in its wall chambers. The structural stiffness-, cavity resonance-, coincidence-, and mass-controlled zones were identified and verified.
