Ventilated Hexagonal acoustic Metamaterial plate based on sided branches Helmholtz resonators with multiple local resonances

The development and application of noise control strategies on subwavelength regimes have thus demanded a continuous effort by several researchers. In this context, the advent of acoustic metamaterials arose as a novel strategy for the manipulation and

Uncertainty characterization and propagation analysis for pneumatic soft acoustic metamaterial system [PDF]

Pneumatic soft acoustic metamaterials have gradually attracted attention inspired by pneumatic soft robots. However, current researches ignore the ubiquitous uncertainty factor, which may cause the designed pneumatic soft acoustic metamaterials to fail ...

Asymmetric frequency conversion with acoustic non-Hermitian space-time varying metamaterial

, 2021
We experimentally realize an acoustic non-Hermitian spacetime varying metamaterial using digital virtualized resonating meta-atoms. By temporally modulating the material gain and loss, we can diminish the main band and achieve high efficiency frequency ...

Broadband Vibration-Isolating Metamaterial for MRI-Induced Vibrations

Archives of Acoustics
The magnetic resonance imaging (MRI) is an important diagnostic tool in medical field. The vibrations originated from the gradient coil of MRI system leads to loud operational noise. The study explores the numerical investigation of elastic metamaterial
