This paper investigated the Eichhornia crassipes as fibers in polymer matrix composite (PMC) for sound absorption. The polyester resin R-108 was mixed with the fibers with the variation percentage. The fibers were varied with three different variations: 20%, 25%, and 30%. The Methyl Ethyl Ketone Peroxide catalyst was added to accelerate the solidification. The sound absorption experiment used a simple insulated box with a sound level meter. After the experiment, the noise absorption coefficient (NAC) result was calculated and analyzed. The maximum noise absorption was obtained at 25% of fibers, indicated by the NAC value of 0.384. In addition, the tensile strength was also obtained for the supplementary data for this study.
