Recently Polymer/natural fiber composites have earning major consideration due to the big
development in non-renewable materials. Many studies were carried out to obtain new …

Plate-type acoustic metamaterials (PAM) consist of a thin plate with periodically added
masses. Similar to membrane-type acoustic metamaterials, PAM exhibit anti-resonances at …

Plate-type acoustic metamaterials (PAM) consist of a thin film with multiple periodically
attached masses. Although these metamaterials can be very lightweight and thin, the …

Thin plate-like metamaterials (eg membrane-type acoustic metamaterials or
inhomogeneous plates) have a high potential for improving the sound transmission loss of …

Acoustic insulator is one the way to overcome noise that can interfere with human health.
The existing acoustic insulator is made of petroleum which affects the environment. Potential …

This chapter introduces the concept of thin films and coatings and then emphasized the
importance and wide applications of thin films and coatings for academic study and …

In this work, we demonstrate in a proof of concept experiment the efficient noise absorption
of a 3D printed panel designed with appropriately arranged space-coiling labyrinthine …

In the present study, a Wave Finite Element-based method is introduced to estimate the
Sound Transmission Loss (STL) of periodic structures with contrasting properties. This …

Sound Transmission Loss (STL) is the difference between sound power in a source room
and a receiver room at a single frequency where both rooms are separated by a partition …
