The new age of fibrous and porous-based composite materials has excellent acoustic
characteristics. Some of the prominent areas where these acoustical materials have found …

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 …

We show experimentally that thin membrane-type acoustic metamaterials can serve as a
total reflection nodal surface at certain frequencies. The small decay length of the …

In this letter, a class of honeycomb acoustic metamaterial possessing lightweight and yet
sound-proof properties is designed, theoretically proven, and then experimentally verified. It …

Due to defects in processing, there are some voids or pores inside the functionally graded
material during the production progress. It has been proved that porosity has been shown to …

This paper reviews the most significant works in literature about the acoustic behaviour of
sandwich panels, starting from the first examples of multi-layered structures, comprising a …

To targeted regulate and improve the low-frequency sound insulation performances of
traditional sandwich structures, a sandwich structure compounded with resonant acoustic …

Lattice structures have numerous outstanding characteristics, such as light weight, high
strength, excellent shock resistance, and highly efficient heat dissipation. In this work, by …

The air-borne sound insulation performance of a rectangular double-panel partition clamp
mounted on an infinite acoustic rigid baffle is investigated both analytically and …
