Sound Absorption Properties of Polyester Fibers Needle-Punched Nonwoven Fabrics
Polyester fiber needle-punched nonwovens with different structures were manufactured and their sound absorption properties were examined using the standing wave tube method. The results show that the sound absorption property of the nonwovens depends on their thickness, needling intensity, fiber diameter and surface structure.
