Broadband impedance modulation via non-local acoustic metamaterials

Zhiling Zhou et al.

Summary: Utilizing nonlocality between subunits, ultrathin acoustic metamaterials achieve broadband sound absorption and desired impedance profiles. The over-damped recipe and the reduced excessive response recipe are employed for impedance matching and broadband near-perfect absorption.

Coupling and scaling effect for low-frequency broadband sound absorption via vertex-based hierarchy

Zhonggang Wang et al.

Summary: This study introduces a hierarchical sound-absorbing meta-structure (HSM) for achieving desired low-frequency broadband absorptive performance at a subwavelength thickness. The physical mechanism behind the superior performance is revealed through coherent coupling effect and hierarchical scaling effect. The experimental results validate the advocated absorptive merits of HSM and show its potential for designing acoustic meta-absorbers against low-frequency noise.

Going Beyond the Causal Limit in Acoustic Absorption

Ho Yiu Mak et al.

Summary: This study demonstrates that by manipulating the boundary condition on the backside of the absorber, near-total absorption of ultralow-frequency acoustic waves can be achieved with a thickness significantly less than the causal minimum. This provides a new design paradigm for ultralow-frequency acoustic absorbers.

High absorption asymmetry enabled by a deep-subwavelength ventilated sound absorber

Houyou Long et al.

Summary: Ventilated sound isolation platforms with asymmetric absorption have significant scientific importance and potential applications. A new paradigm to achieve high absorption asymmetry is proposed by coupling a lossy meta-atom with a non-resonant impedance boundary in a deep-subwavelength ventilated absorber. The design includes a folded Fabry-Perot resonator and a narrow slit channel, allowing for flexible frequency modulations and construction of broadband asymmetric absorbers. The results suggest potential for developing ultrathin ventilated functional devices capable of absorbing sound asymmetrically.

Broadband low-frequency sound absorbing metastructures based on impedance matching coiled-up cavity

Yiyang Liu et al.

Summary: This study presents a sound absorbing metastructure based on micro-perforated panel (MPP) and impedance matching coiled-up cavity (IMCC), which greatly expands the low-frequency working bandwidth within a deep sub-wavelength thickness. The impedance matching reduces the acoustic reactance variation with frequency, leading to broader low-frequency bandwidth. Theoretical predictions coincide well with numerical and experimental results, contributing to expanding design freedom for manipulating low-frequency waves.

Nonlocal acoustic metasurface for ultrabroadband sound absorption

Yifan Zhu et al.

Summary: The study introduces the concept of a nonlocal acoustic metasurface absorber using a bridge structure to improve performance, achieving ultrabroadband sound absorption with deep-wavelength thickness. The nonlocality introduces three specific effects, optimizing effective acoustic impedances, shifting Fabry-Perot resonant frequencies, and enhancing coupling effects between adjacent unit cells, contributing to improved bandwidth and efficiency.
