Benchmark cases are of interest throughout the computational acoustics wide community, and are defined for all fields of physical acoustics. Thereby, we have the following categories:
Wave propagation as a solution of the wave equation, including scattering and radiation problems, interior and exterior problems, time domain and frequency domain problems.
High frequency acoustics
Higher frequency problems for which consideration of energy terms might be more interesting than deterministic evaluation acoustic quantities such as pressure or particle velocity.
Acoustics and vibration
Fluid-structure interaction problems, including transmission loss through (layered) plates and shells, structure, porous media.
Flow- and aeroacoustics (with coupling to structural vibrations), underwater acoustics.
