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 …

Nowadays the use of porous polyurethane sponge (PPS) is very common for sound
absorption, thanks to its light-weight feature and easy fabrication. However, in many …

Acoustic black hole (ABH) indentations on plates are very efficient to reduce high frequency
vibrations. However, when the wavelength of the im**ing bending waves on the ABH is …

Acoustic black holes (ABHs) have been found to exhibit desirable dam** characteristics
for vibration attenuation of thin-walled structures. However, up until now, no research has …

Acoustic black holes (ABHs) attract increasing attention in the field of vibration suppression,
sound radiation control and energy harvesting. Though the ABH effect usually works well in …

While acoustic black holes (ABHs) are well-known inefficient at low frequencies. However,
attaching periodic local resonators to form a metamaterial ABH (MMABH) plate could be …

This paper first suggests a composite structure with periodic additive acoustic black holes
(ABH) to absorb vibrations from plates. Different from conventional embedded ABHs, this …

Acoustic black holes (ABHs) have been shown very efficient to reduce sound radiation in the
air. However, their underwater performance is not clear. In this paper, we consider a Mindlin …

Add-on acoustic black holes (ABHs) tend to be popular in recent years because it is not
mandatory to diminish the thickness of the host structure. Instead, ABHs are treated as …
