Improvement of the sound absorption of flexible micro-perforated panels by local resonances

To further improve the sound absorption enhancement of flexible micro-perforated panels (FMPPs), a new sort of perforated sound absorbers - metamaterial-based micro-perforated panels (MMPPs) - is proposed by combining a micro-perforated host panel and local resonators (LRs) attached on a sub-wavelen...
