Finite element techniques were first developed for analysing complex, engineering structures. Once the method had been given a firm mathematical foundation, it was only natural that it should be used for analysing other physical problems which could be represented by partial differential equations. The field of acoustics has been no exception.

Acoustic bodies will be defined in Mechanical, so there is no real need of defining material properties in the Engineering Data. However, it is a good practice to duplicate the default material – which more than often is Structural Steel – and to create 3 materials from the library: Bard, D, Negreira, J, Kouyoumji, JL, Borello, G & Guigou, C 2014, Challenges for acoustic calculation models in "silent timber build", Part 1- FEM. i J Davy, M Burgess, C Don, L Dowsett, T McMinn & N Broner (red), INTERNOISE 2014 - 43rd International Congress on Noise Control Engineering: Improving the World Through Noise Control.

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.

In order for a product to be accepted by customers, manufacturers must pay close attention to its acoustic signature, both for branding purposes and to limit noise pollution. FEM/FMBEM coupling for acoustic structure interaction and acoustic design sensitivity analysis with sound-absorbing materials Y. M. Xu, H. B. Chen & L. L.
