title = "Research on sound insulation of multiple-layer structure with porous material and air-layer",
abstract = "Sound insulation performance of multiple-layer structure is investigated which consists of elastic solid, fluid and porous material. The Biot theory of sound propagation in elastic porous medium and the method of transfer matrix are used to derive the transmission loss of typical layered-structure. The influence of air-layer and porous material on sound insulation performance of multiple-layer structure had been discussed by numerical calculation and experimental testing. The result indicates that the air-layer and porous material can improve sound insulation performance of multiple-layer structure and their distribution also has great influence on the sound insulation performance.",
