By leveraging the resonance and anti-resonance effects of macroscopic locally resonant units, together with the mass and damping effects introduced by microscopic particles, MSAM can achieve multi-scale energy dissipation, effectively improving the low-frequency sound insulation performance of thin-plate-type acoustic metamaterials. Meanwhile, the in-plane non-uniform distribution broadens the working frequency band. The research on MSAM shows that the introduction of particles introduces additional design parameters for thin-plate-type acoustic metamaterials. By adjusting the particle filling ratio, the mass and damping effects of MSAM can be modulated, enabling excellent frequency and amplitude tunability in the low-frequency range.
