In this paper, four kinds of natural fibers (cotton, wool, silk and ramie) are studied. Three experimental programs are designed, and influence factors of sound absorption properties of porous sound absorption material are discussed. With the change of material thickness and cavity length, the variation of sound absorption coefficient is obtained in different noise frequency.
