Numerical simulations of the radiation and scattering of sound have
become a valuable tool for the design of structures with respect to
their acoustic behaviour. To this end several commercial software
packages have been developed, which are based on the finite element
method (FEM) or the boundary element method (BEM) or combinations
of both numerical methods. They can be employed for the numerical
prediction of the sound field, which is radiated by vibrating
structures or scattered by structures. In addition, some software
packages offer the possibility of coupled elasto-acoustic analyses,
which take account of the interactions between the sound pressure
field in a fluid, surrounding an elastic structure and the dynamic
behaviour of the structure. Such coupling effects may be important,
e.g., for very thin membranes.
The proposed benchmarks refer to acoustic analyses for uncoupled
problems by the BEM, i.e, to sound radiation by vibrating
structures or the scattering of sound by structures. Coupling
effects between structures and acoustic media are neglected.
