The effects of different thickness on morphology and acoustic properties of oil palm empty fruit bunch with density of 140 kg/m3

This research investigates the Sound Absorption Coefficient (a) of Empty Fruit Bunch (EFB) fiber with density of 140 kg/m3 which were fabricated at four different thickness of 14 mm, 15 mm, 16 mm and 17 mm. Urea Formaldehyde (UF) glue was used as binder with amount of 20% from fiber weight. Then, Sc...
