Abstract

This research was carried out to study the acoustic properties of two natural organic fibres; coir and oil palm fibres. During the processing stage, coir fibre sheet has been treated with latex and the oil palm fibre sheet has been treated with PVA. Both are compressed under pressure using high precision hydraulic machine for 30 minutes to form the fibre sheets. The density of the coir fibre sheet is determined to be 74 kg/m3 while the density of the oil palm fibre is 130 kg/m3. Both fibre sheets were tested at acoustic lab, Faculty of Engineering and Built Environment, Universiti Kebangsaan Malaysia using ISO 354 (1985) standard for noise absorption coefficients to determine their noise absorption coefficient. The results obtained show that the coconut coir fibre gives an average noise absorption coefficient of 0.50. It shows a good noise absorption coefficient for higher frequencies but less for the lower frequencies. The oil palm fibre gives an average noise absorption coefficient of 0.64. The oil palm fibre shows a good noise absorption coefficient for higher frequency region compared to lower frequency region. The oil palm fibre shows a higher noise absorption coefficient due to its higher density. Both fibre have a high potential to be used as a sound absorber materials.
