Abstract
One method to absorb noise is by using acoustic absorber. Empty fruit bunch fibres (EFB) and mesocarp fibres (MF) are waste materials generated from palm oil mills. This research aimed to fabricate sustainable acoustic absorbing particleboard using EFB and MF to replace conventional materials currently used. Two parameters that were investigated are the mix ratio of the EFB and MF and the addition of binder (urea formaldehyde, UF) into the fibres. Sample thickness was maintained at 20 mm and 30 mm for samples with and without binder. The sound absorption coefficient (SAC) of the samples were tested using an impedance tube according to ISO 10534 – 2 standards. Samples produced using 50% EFB and 50% MF with and without binder shown the best SAC of 0.699 and 0.982 at 1200 Hz respectively. This is equal or better than conventional materials such as mineral wool with SAC values of 0.875 at 1000 Hz. Swelling test however shown that all samples do not meet the criteria by JIS A 5908 for particleboard. Future studies could include the use of green binder and different percentages of EFB, MF and binder.
