LAMINATED SOUND ABSORBING MATERIAL

The present invention addresses the problem of providing a sound absorbing material which exhibits excellent sound absorbing performance in low-frequency and intermediate-frequency ranges, and preferably also in higher-frequency ranges. This laminated sound absorbing material includes at least: a fiber layer; and a porous layer, wherein the fiber layer has an average flowrate fine pore diameter of 1.0-60 |am and an air permeability as measured with a Frazier from method of 30-220 cc/cm2·s, and the porous layer comprises at least one selected from the group consisting of foamed resins, unwoven fabrics, and woven fabrics, has a thickness of 3-40 mm and a density of 3-50 kg/m3 which is lower than that of the fiber layer, and is disposed such that the fiber layer is on the sound entry side.
