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 …

Structural materials that feature hierarchical architectures (eg, fractals) display remarkable
mechanical properties. Menger sponge is one of the fractal geometries defined in …

This paper proposes a bandwidth-limited passive noise control system enabled by an
acoustic superscatterer to suppress the far-field sound radiated from a vibrating cylindrical …

Noise has a negative impact on our environment and human health. For this reason, it is
necessary to eliminate excessive noise levels. This paper is focused on the study of the …

An array of Helmholtz resonators is a potential solution to attain the tuned acoustic
attenuation in low frequency regime where the higher bandwidth over individual Helmholtz …

It is estimated that approximately 1.2 million tons of cigarette butts (CBs) are introduced into
the environment annually. The aim of this work is to analyze the incorporation of shredded …

Effective direct control of the sound source is the fundamental solution to the problem of
noise. Herein, we propose a passive, non-closed and remote scheme for omnidirectional …

Acoustic attenuation of a hybrid sonic crystal made with periodic cylindrical scatterers and
cascaded porous panels in a broad frequency range is endeavoured in this paper. It is …

This paper presents a theoretical approach to assess the effective sound propagation
properties of an acoustic system comprising multiple subwavelength resonators under …

The sound transmission loss across a duct muffler in the form of a linear array of 11 narrow
sidebranches is examined experimentally in the present study. The introduction of a low …
