Abstract

The following research presents the development of natural fiber-based nonwovens as a potential substitute for acoustic materials commonly made of synthetic and mineral fibers and an analysis of variance (ANOVA) which deals with the effect of fiber size, density, and binder content in the sound absorption coefficient of such materials. The characterization of the fibers showed the potential of denim fibers, which could easily outperform fique and coir, which was later confirmed in the acoustic tests. The analysis of variance showed that density and fiber size had a significant effect on the sound absorption coefficient. Denim nonwovens presented a sound absorption comparable to glass fiber-based materials, thus, demonstrating the technical potential of natural fibers to replace traditional materials.
