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:

  1. Linear acoustics:
    Wave propagation as a solution of the wave equation, including scattering and radiation problems, interior and exterior problems, time domain and frequency domain problems.

  2. 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.

  3. Acoustics and vibration:
    Fluid-structure interaction problems, including transmission loss through (layered) plates and shells, structure, porous media.

  4. Acoustics involving heterogeneous and moving fluids:
    Flow- and aeroacoustics (with coupling to structural vibrations), underwater acoustics.
