Marine anthropogenic noise has increased significantly over the past few decades, and a
growing body of research is highlighting the negative impacts this is having on marine eco …

Polymer foams have low density, good heat insulation, good sound insulation effects, high
specific strength, and high corrosion resistance, and are widely used in civil and industrial …

Although mutually independent, simultaneous sound absorption and superior mechanical
properties are often sought after in a material. One main challenge in achieving such a …

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 …

It is of significance, but still remains a key challenge, to attain excellent sound-absorbing and
mechanical properties in a material simultaneously. To overcome this challenge, herein …

Owing to the pervasive noise and crash hazards, tough microlattices with sound absorption
capabilities are sought-after. However, typical truss microlattices are unable to fulfill this …

In recent years, noise pollution has become one of the most critical human environmental
problems. It has adverse effects on people's health and their work efficiency. Therefore …

This work presents benchmark examples related to the modelling of sound absorbing
porous media with rigid frame based on the periodic geometry of their microstructures. To …

An innovative natural fibro-granular composite made of kenaf fibers and waste rice husk
granules is developed and presented in this paper. The optimization of the sound absorption …

In this study, hybrid composites made of polyurethane (PU) matrix and natural kenaf fiber
filler were designed and fabricated. The Response Surface Methodology (RSM) optimization …
