Abstract

Labyrinthine structures that increase the wave-path length can be used as an acoustic liner to attenuate sound in ducts while allowing net air flow. In this study, the performance of ventilated labyrinthine metamaterials is assessed utilizing a homogenized equivalent fluid continuum. The effective domain is a more computationally efficient way to compute the pressure field compared to direct numerical simulation thanks to a coarser mesh.
