Acoustical FEM can be easily coupled with structural FEM, which is already well-known to most structural analysts. The acoustical and structural coupling in the The finite element method (FEM) for acoustics analysis is ideal for simulating interior acoustics problems. In addition to FEM being the more efficient method in terms of solution speed, FEM acoustics lets you perform coupled vibro-acoustics analyses that take structural modes and soundproofing materials into consideration.

and performance of a FEM code able to compute the propagation of acoustic waves in ducts characterized by pointwise-variable mean compressible flow. The accuracy of conventional FEM/BEM for structural-acoustic problems strongly depends on the size of the mesh, element quality, etc. As element size gets Defining spatially varying fluid properties in acoustic analysis . The finite element representation of acoustic elements is similar to that in conventional Finite element method (FEM) and boundary element method (BEM) are methods usually applied on low-frequency coupled fluid-structure analysis.

Predicting the acoustic response for a large volume in the audio range or around a big geometry (airplanes, cars or even a city!) is prohibitive from a computational point of view using classic Finite Element Method (FEM) or Boundary Element Method (BEM).

The field of acoustics has been no exception.
