dc.description.abstractOil palm is only second to soybean when it comes to be the source of edible oil. Malaysia is among the primary producers and exporters of palm oil in the world. Oil Palm Empty Fruit Bunch (OPEFB) is the main byproduct among the oil palm biomass with about 18 million tons produced yearly. About 20% of empty fruit bunch can be extracted from a fresh oil palm fruit bunch. Therefore, oil palm wastes pose major threats towards Malaysia in disposing the excess material. Producing materials from OPEFB natural fibers can minimize and recycle the waste to our environment. This paper reports the acoustic performance of OPEFB in different densities of 120, 140, 160 and 180 kg/m3 with constant thickness of 14 mm. Two type of fibres were studied which are Short Strand Fibre (SSF) and Fined Fibre (FF) and compared. Total of 8 fibreboards (4 SSF and 4 FF) were produced and tested by using Impedance Tube Method (ITM). Two targeted density, which were SSF samples with 160 and 180 kg/m3, able to achieve SAC of 0.88 in frequency range of 4500 – 5000 Hz. The FF samples with density of 160 and 180 kg/m3 were able to achieve unity (SAC > 0.97) at wider frequency range of 4000 – 5000 Hz. The acoustic performance of FF can perform better when compared with SSF at all frequency range.en_US
