Abstract The Acoustic Black Hole (ABH) is a technique for passive vibration control that was
recently developed within the Structural Dynamics and Vibroacoustics communities. From a …

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 …

In this letter, it is suggested to attach acoustic black holes (ABHs) on a base beam with
gradient parameters for wave attenuation in ultrawide bands. Three types of metabeams …

Acoustic black hole (ABH) indentations on plates are very efficient to reduce high frequency
vibrations. However, when the wavelength of the impinging bending waves on the ABH is …

In this work we first propose a wave and Rayleigh–Ritz method (WRRM) to analyze the
vibrations of periodic systems. It is well-known that one of the main difficulties of the …

Acoustic black holes (ABHs) have been found to exhibit desirable damping characteristics
for vibration attenuation of thin-walled structures. However, up until now, no research has …

Acoustic black holes (ABHs) attract increasing attention in the field of vibration suppression,
sound radiation control and energy harvesting. Though the ABH effect usually works well in …

We present the double-leaf acoustic black hole beam embedded mass oscillator, and
discuss the different elastic waves modulation effects. Vibration transmission spectrum …

Acoustic black holes (ABHs) achieved by thinning structural thickness following a power-law
profile have shown fantastic applications in vibration and noise suppression, energy …

While acoustic black holes (ABHs) are well-known inefficient at low frequencies. However,
attaching periodic local resonators to form a metamaterial ABH (MMABH) plate could be …
