Perforation Enhances Sound Insulation in Plate Lattice Metamaterials

Small, EarlyView.
Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...
