摘要：
This paper presents the sound absorption coefficient performance of kenaf fibre with added perforated plates. The low frequency absorption is improved with the introduction of perforated plates sandwiched between the fibre layer and the air cavity. The drawback of such combination is the dropped performance in higher frequency. Mathematical models were used to simulate predicted sound absorption coefficient.
