Noise pollution has become a significant global problem in recent years. Unfortunately,
conventional acoustic materials cannot offer substantial improvements in noise reduction …

This study collects all of the existent papers in the field of acoustic transmission across
multilayered plate constructions. Herewith, a comprehensive source is proposed wherein …

Triply periodic minimal surface (TPMS) sandwich panels have superior characteristics,
including lightweight and extraordinary mechanical properties, so that they are widely …

According to the mass law, a dense and thick soundproofing material is generally used to
block low-frequency sounds. However, lightweight thin soundproofing materials in the form …

Acoustic metamaterials have been becoming a popular topic for the better sound insulation
at low frequency than traditional materials. However, due to the local resonance mechanism …

Low-frequency and broadband noise reductions have always been a major industrial
concern, as they pose a significant challenge. Although acoustic metamaterials are …

This study proposes the use of a linear and geometrically nonlinear inerter-based resonator
in locally resonant acoustic metamaterials (LRAMs) and evaluates the performance on low …

As one of the representatives of acoustic metamaterials, the membrane-type acoustic
metamaterial has excellent sound insulation performance due to its locally resonant …

Sound absorption performance of the Helmholtz resonator was enhanced by space division
and chamber grouping in this research, which aimed to achieve high sound absorption …

As a subcategory of acoustic metamaterials, membrane acoustic metamaterials (MAMs) are
lighter and more adjustable than other types of acoustic metamaterials when it comes to low …
