title = "FLEXIBLE PERFORATED MEMBRANE-TYPE ACOUSTIC MET-AMATERIAL WITH LOW-FREQUENCY BROADBAND SOUND ABSORPTION",
abstract = "In this study, we creatively propose to use flexible thin film instead of ordinary Helmholtz resonator (HR) hard upper surface to achieve second-order or higher-order near-perfect sound absorption flexible perforated thin film Helmholtz resonant cavity (FPFHR). To be exact, the flexible film with abundant vibration modes at low frequency is used to replace the hard material, so as to realize multi-peak resonance sound absorption. We studied the sound absorption mechanism of FPFHR unit, carefully analyzed the influence of key structural parameters of FPFHR unit on its sound absorption performance, designed 6 FPFHR units to realize low frequency wide band absorption. This work has far-reaching significance for the discovery of more low-frequency broadband absorption structures, and shows great potential in noise control.",
