The boundary element discretization of the acoustic Helmholtz equation yields frequency-dependent linear systems, which require efficient solution strategies for multi-frequency analysis. We briefly review recent advances in this field covering frequency approximation and extraction of coefficient matrices, frequency sampling strategies, iterative solvers for frequency-dependent linear systems and model order reduction techniques.
