Hierarchical-porous acoustic metamaterials: A synergic approach to enhance broadband sound absorption
A novel design for hierarchical-porous acoustic metamaterials (HPAM) is proposed to enhance the functionality of Helmholtz-type resonators and porous materials, achieving continuous and efficient broadband sound absorption. This method can potentially eliminate absorption valley and improve the coup...
