In recent years, increasing attention has been paid to the impacts of environmental noises
on living creatures as well as the accuracy and stability of precise instruments. Due to …

In rods and beams, piezoelectric patches with external circuits have been extensively
studied to dampen structural vibrations at the sound source. This work uses a large flat-layer …

Integrating soft components into acoustic metamaterials is an extremely promising way to
enhance their adjustability and reconfigurability. Herein, we report a type of space-coiled …

This paper proposes a novel multifunctional ultra-thin membrane based on a
Polyborosiloxane-based gel with stimuli-responsive sound absorption and sound …

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 new micro perforated sandwich panel with honeycomb-hierarchical pore structure core is
designed and prepared in this study. Carbonized cotton with hierarchical pore structure is …

A noise with multiple tonal components is prevalent in practice, and these tones, contributing
to noise annoyance, may even span several octaves and the frequencies of them always …

A micro-perforated plate (MPP) as a typical acoustic absorber has ideal sound absorption
performance at mid-frequency. A novel metastructure with a MPP and multiple sub-cavities …

This paper proposes an algorithm to perform the inverse design of a low-frequency acoustic
absorber using a deep convolutional autoencoder network. A hybrid sound-absorber …

Acoustic deficiencies due to lack of absorption in indoor spaces may sometime render
significant buildings unfit for their purpose, especially the ones used as speech auditoria …
