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

Acoustic metamaterials (AMs), which are materials composed of subwavelength periodic
artificial structures with specific designs, have drawn significant research attention. This is …

Many advanced physical properties can be realized by using well-designed acoustic
metamaterial (AM) structures, which have significant application value in engineering. In …

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 …

Lattice truss-core sandwich plates have drawn increasing attention owing to their excellent
mechanical properties and multifunctional characteristics, but they are insufficient in low …

This paper presents a design for a sandwich-like plate containing mass-beam resonators to
obtain a specific and low-frequency stopband. The resonators consist of a cantilever beam …

Owing to a steep rise in urban population, there has been a continuous growth in
construction of buildings, public or private transport like cars, motorbikes, trains, and planes …

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 …

We propose a multi-order Helmholtz metamaterial with deep-subwavelength thickness in
which perfect continuous acoustic absorption is achieved within 400 Hz∼ 2800 Hz. The …

Despite the emergence of acoustic metamaterials with superior sound absorption and
transmission loss, their adoption for building sound insulation has been limited. Sound …
