The manipulation of acoustic waves is becoming increasingly crucial in research and
practical applications. The coordinate transformation methods and acoustic metamaterials …

In this work, the idea of metamaterial-based absorbers is further extended to develop the
concept of sound and vibration absorbers (SVA) capable of simultaneously absorbing sound …

A hybrid honeycomb structure (HHS) with energy dissipation enhancement effect is
proposed for broadband underwater sound absorption. The HHS is constructed using …

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 …

A novel three dimensional underwater smart piezo-sandwich spherical shell cloak is
designed and analyzed based on the hybrid active/semi-active distributed structural acoustic …

Resolving the trade-off problem between wave obstructing and flow transport is an intriguing
but challenging task that may find potential applications in many noise control scenarios …

Non-visual auditory camouflage plays a major role in the art of underwater deception. In this
work, a hybrid active/semi-active omnidirectional cloaking shell structure composed of …

Metamaterials have been widely studied in recent years, setting out their various exotic
properties, but typically passive configurations are discussed, with limitations in frequency or …

Ventilation noise control devices often involve a trade-off between their size and ventilating
performance, which limits the ability to reduce low-frequency sound in high-ventilation …
