    Design optimization for broadband sound insulation by double-panel structure with a slot-type Helmholtz resonator array at low frequency range

    In this paper, a numerical study is conducted to optimize the double-panel structure with a locally resonant sonic crystal for the band reduction of the low-frequency sound transmission. Recently, we proposed ...
