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 …

Metamaterials are attracting increasing interest in the field of acoustics due to their sound
insulation effects. By periodically arranged structures, acoustic metamaterials can influence …

While acoustic black holes (ABHs) are well-known inefficient at low frequencies. However,
attaching periodic local resonators to form a metamaterial ABH (MMABH) plate could be …

Acoustic black holes (ABHs) have been shown very efficient to reduce sound radiation in the
air. However, their underwater performance is not clear. In this paper, we consider a Mindlin …

Add-on acoustic black holes (ABHs) tend to be popular in recent years because it is not
mandatory to diminish the thickness of the host structure. Instead, ABHs are treated as …

Annular acoustic black holes (ABHs) have been recently proposed as a potential means for
reducing vibrations of cylindrical shells. The latter are very common structures in the naval …

In this paper, we consider a composite cylindrical shell having an internal thin plate. When
some ABHs are embedded on the interior floor, the vibration of the cylindrical shell and the …

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 …

The inverse boundary element method (IBEM) is a powerful tool for realizing sound field
reconstruction of sources with arbitrarily-shaped surfaces. In the conventional IBEM, the …

Vibrating structures have received considerable critical attention as they radiate sound into
enclosures where it is amplified by reflections. Surface and panel contribution analyses …
