Because nonwoven fabrics can significantly attenuate acoustic energy through their high porosity and small fiber diameter, they have been widely used as sound-absorbing materials in various industries. Along with microfiber nonwoven fabrics, novel nanofiber nonwoven fabrics possess excellent sound absorption properties owing to their fineness. In this study, the sound absorption characteristics of composite materials composed of microwebs and nanowebs were carefully investigated using a stacking structure and the number of layers.
