The purpose of this research is to develop sound insulation panel from oil palm fiber (OPF). The study compared panels made from OPF with other acoustic panels in the market. This raw material is a byproduct from agricultural harvest. Hot press technique with the pressure of 400 kg/m3 was used to create the panel with the thickness of 20 mm. The temperature during the compression was 150°C, and the force used for pressing the panels for 8 minutes ranged between 25-30 kg/m2. The amount of pMDI applied as a binding agent was 5% by weight of the panel. Sound absorption tests were carried out in a test box with sound level meters. The results of the tests showed that the sound-absorbing property of the developed OPF panels with holed surface is greater than that of the traditional OPF panels and acoustic boards. It was found that different sizes and patterns of holes have an effect on sound-absorbing capacity. The developed OPF panels showed a good sound-absorbing capability in medium-to-high frequency (500 Hz – 2000 Hz). The best sound insulation panel made from OPF is the panel with a 5% by weight of pMDI and has a density of 400 kg/m3. The physical and mechanical properties of the panels comply with the standard of strength and mechanical properties of soft boards (Library of Congress Cataloging – In – Publication Data).
