Abstract: Disclosed is an acoustic absorbent including a fiber web formed of a melt-blown fiber and a polypropylene staple fiber, wherein the melt-blown fiber is prepared by melt-extruding a resin composition including a homo polypropylene and a polypropylene-based elastomer. Tensile elongation of the acoustic absorbent is improved as the content of the polypropylene-based elastomer increases. Due to excellent fitting property, the acoustic absorbent has excellent fitting property and, thus, can be efficiently fixed in a product with a complicated surface appearance. Further, by using a predetermined content of a polypropylene-based elastomer, the acoustic absorption performance of the acoustic absorbent is considerably improved.
