Practical vibroacoustic systems involve passive acoustic treatments consisting of highly dissipative media such as poroelastic materials. The numerical modeling of such systems at low to mid frequencies typically relies on substructuring methodologies based on finite element models. Namely, the master subsystems (i.

- Modeling complex vibroacoustic systems using finite element methods can be impractical, leading to preference for analytical methods like the transfer matrix method, which provides quick estimates but lacks geometric accuracy.
- The transfer matrix method is limited to high frequency ranges due to strong underlying assumptions.
- A proposed hybrid methodology combines the flexibility of finite element methods with the efficiency of transfer matrix methods, demonstrating reduced computational effort while maintaining reasonable accuracy in predicting vibroacoustic indicators for flat structures with acoustic treatments.
