Improvement of Sound Insulation Through Double-Panel Structure by Using Hybrid Local Resonator Array

Improvement of Sound Insulation Through Double-Panel Structure by Using Hybrid Local Resonator Array

In this paper, we present one approach to improve the soundproofing performance of the double-panel structure (DPS) in the entire audible frequencies, in which two kinds of local resonances, the breathing-type resonance and the Helmholtz resonance, are combined. The thin ring resonator row and slit-...
