Natural Silencer : Assessing the Acoustic Excellence of Fiberboard Composites Derived from Sawdust and Coconut Husk Fiber for Soundproofing

As societal evolution progresses, contemporary construction practices are witnessing a notable shift towards heightenedinnovation in material selection and utilization. In response to this trend, there has been a discernible rise in the adoption oforganic and natural materials, driven by their perceived efficacy in providing cost-effective alternatives to conventionalcounterparts. Recent findings have unveiled the intrinsic sound-absorbing properties inherent in sawdust and coconut fiber husk,previously considered as natural waste, thereby highlighting their potential to significantly mitigate environmental noisepollution within our living environment. This study explores the viability of utilizing natural and organic substrates, namelysawdust and coconut fiber husk, for the production of acoustic fiberboards. The composite demonstrates satisfactoryperformance across various tests, including sound absorption, compressive strength, moisture content, water absorption, and fireresistance. The findings about the fiberboard indicate a notable impact on both the thickness of the samples and the compositionratio. The adoption of sawdust and coconut fiber in fiberboard manufacture provides more efficient sound absorption overcommercially available materials. These findings suggest the potential for developing eco-friendly alternatives for fiberboardsusing agricultural waste.
