Novel Design Scheme for Structural Fundamental Frequency of Porous Acoustic Metamaterials

Structural resonance increases the vibration and noise of porous acoustic metamaterials while reducing the energy consumption and conversion efficiency of acoustic waves. Therefore, structural fundamental frequency of porous acoustic metamaterials is required to be controlled to avoid resonance. Thi...
