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 …

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 …

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

Acoustic black holes (ABHs) have been so far investigated mainly for flexural wave
manipulation in structures. Exploration of ABHs for sound wave manipulation, referred to as …

An acoustic black hole (ABH) beam termination can be achieved by decreasing its thickness
according to a power-law profile. Waves entering the ABH slow down and vibrational energy …

Power-law profiles at the edges of beams and plates have proved to be a very efficient way
to attenuate vibrations. In an ideal scenario, for a profile with zero end thickness, the energy …

Reduction of vibration and sound energy in the form of traveling waves is of vital importance
in many applications. Recent development of acoustic metamaterials opens up unusual …

In this evolving technology, we move towards a more comfortable and swifter life, which
comes with certain drawbacks. Among them, noise finds one of the prominent places due to …

In this paper, we suggest a metabeam having periodically distributed integrated acoustic
black holes (IABHs). Compared to conventional embedded ABHs, the thickness of the base …

Wideband reduction of both sound reflection and transmission using compact non-intrusive
liners remains a challenging issue for duct noise control applications. This work focuses on …
