The traditional sound absorption problem has not been completely resolved over the last
200 years. At every stage, its research has changed depending on practical requirements …

In order to improve and broaden the sound absorption performance of porous materials with
low flow resistance, this study proposes the composite meta-porous structure embedded …

Technological advancement, the high cost of energy, and the continuous growing demands
of multitasking devices are the driving forces behind the huge market of compact …

This study aims to demonstrate the reduction in noise and vibration of an automobile dash
panel structure by applying a locally resonant metamaterial (LRM). LRMs are implemented …

We theoretically and experimentally investigate visco–thermal effects on the acoustic
propagation through metamaterials consisting of rigid slabs with subwavelength slits …

This paper explores a new approach to reducing the interior noise of one vehicle body
through the flexural wave bandgap. The phononic crystal is designed by attaching the …

Traffic noise has increased in recent years and hence the European Union has regulated
the noise emission norm more strictly. New technologies have to be developed to reach the …

The proposed numerical design approach investigates both infinite and finite models and
includes an experimental validation of elastic wave absorption and vibration suppression for …

To further improve the sound absorption enhancement of flexible micro-perforated panels
(FMPPs), a new sort of perforated sound absorbers–metamaterial-based micro-perforated …

This work discusses many practical and some theoretical aspects concerning modelling and
design of plates with micro-slits, involving multi-scale calculations based on microstructure …
