This work presents benchmark examples related to the modelling of sound absorbing
porous media with rigid frame based on the periodic geometry of their microstructures. To …

Given the quest for mass reduction while preserving proper vibration and acoustic comfort
levels in industrial machinery and vehicles, lightweight poroelastic materials have gained a …

This study mainly focuses on the structural design, acoustic performance prediction, and
experimental validation of a novel composite sound absorber that is similar to the feather …

Transport parameters play a key role in characterizing the thermo-viscous behaviour of the
microgeometry. Semi-phenomenological models provide valuable tools to establish a …

We present a simplistic yet accurate unit cell model of sound absorption for highly porous
foams having either fully-open or semi-open cells. Employing an idealized periodic cubic …

This paper proposes and discusses an approach for the design and quality inspection of the
morphology dedicated for sound absorbing foams, using a relatively simple technique for a …

Cellular foams with randomly distributed open pores are increasingly exploited in sound
management applications, where the sound absorption coefficient (SAC) typically serves as …

It is shown that three-dimensional periodic unit cells (3D PUC) representative of transport
parameters involved in the description of long wavelength acoustic wave propagation and …

A semi-analytical model is developed to predict the influence of temperature on the sound
absorbing performance of sintered metal fiber materials (SMFMs) by extending the Johnson …

A general and widely tunable method for the generation of representative volume elements
for cellular materials based on distance and level set functions is presented. The approach …
