The boundary element method (BEM) in the context of acoustics or Helmholtz problems is
reviewed in this paper. The basis of the BEM is initially developed for Laplace's equation …

Noise barriers are the most widespread solution to mitigate noise produced by the
continuous growth of vehicular traffic, thus reducing the large number of people exposed to it …

A strong-form boundary collocation method, the singular boundary method (SBM), is
developed in this paper for the wave propagation analysis at low and moderate …

The modern scope of boundary element methods (BEM) for acoustics is reviewed in this
paper. Over the last decades the BEM has gained popularity despite suffering from …

Noise attenuation by sonic crystal noise barriers occurs mainly in specific frequency bands
(bandgaps), due to a mechanism called Bragg scattering, which is the result of destructive …

This chapter presents an introduction to the solution of time-harmonic acoustic problems by
a boundary element method (BEM). Specifically, the Helmholtz equation with admittance …

In this work, two fast multipole boundary element formulations for the linear time-harmonic
acoustic analysis of finite periodic structures are presented. Finite periodic structures consist …

This paper presents a hybrid wave and finite element/boundary element method for
predicting the vibroacoustic characteristics of complex panels characterised by an irregular …

An efficient boundary element formulation is proposed to solve three-dimensional exterior
acoustic scattering problems with multi-directional periodicity. The multi-directional periodic …

The use of periodic structures in acoustic applications has interested the scientific
community in the last two decades. Although in-depth research has been thoroughly …
