“…Hence, for a reasonable NVH level at lower frequencies, heavy and bulky additions are often required. There are also several avant-garde techniques, including utilizing porous liners [36], perforations [37], and auxetic structures [38], which have been mostly employed in the automotive industries to control NVH issues. Auxetic materials have an abnormal property called negative Poisson's ratio (NPR), allowing them to expand laterally under an axial tensile force.…”

“…The metamaterial plates with adjustable band gaps by adjusting the stiffness ratio [19], monostable acoustic metamaterial absorber [20], etc. While, the bandwidths of LR band gaps are typically narrower compared to those of Bragg gaps, this may pose some limitations in practical engineering applications [21,22].…”
