In recent years metamaterials gained a lot of attention due to their superior noise and
vibration insulation properties, be it at least in some targeted and tuneable frequency …

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 …

Recently, locally resonant metamaterials have come to the fore in noise and vibration control
engineering, showing great potential due to their superior noise and vibration attenuation …

This paper provides a unified approach to evaluate the sound absorption performance of the
metamaterial microperforated panel (MMPP) with additional local resonators under elastic …

Vibro-acoustic locally resonant metamaterials with structural stop band behaviour can lead
to a strongly increased sound transmission loss in a targeted frequency range. This work …

Double panel partitions with a foam core suffer a poor sound transmission loss at their mass-
spring-mass resonance frequency. This paper considers the use of vibro-acoustic resonant …

Environmental and economic requirements lead to a constantly increasing application of
lightweight designs. Fulfilling the conflicting goals of favorable noise and vibrational …

Locally resonant metamaterials are employed to increase the sound insulation of a host
structure. In orthotropic host structures, the direction-dependent bending stiffness leads to a …

This paper investigates a metamaterial solution for efficient vibration attenuation and
acoustic radiation reduction of an aluminum pipe. To this end, using unit cell predictions …

The design of structures that can yield efficient sound insulation performance is a recurring
topic in the acoustic engineering field. Special attention is given to panels, which can be …
