The Potential of Sawdust and Coconut Fiber as Sound Reduction Materials

In this study, biodegradable materials that could be utilized to reduce noise were examined. Sound absorption test was conducted with an impedance tube. Sawdust, coconut fiber, and expansive clay used create samples. Noise reduction coefficient results for sawdust mixture ranged from 0.24 0.62. A of fiber recorded in between 0.31 0.58. Coconut mixed ranging The study findings suggests these have good acoustic properties can therefore as alternative materials. These important implications reducing environmental pollution if adopted the development
