Vibrational Effects on the Acoustic Performance of Multi-Layered Micro-Perforated Metamaterials
Broadband noise reduction over the low–mid frequency range in the building and transportation sectors requires compact lightweight sound absorbers of a typical subwavelength size. The use of multi-layered, closely spaced (micro-)perforated membranes or panels, if suitably optimized, contributes to t...
