Characterization of The Acoustical Absorption of Woven Agel Fibre Sheet (Corypha utan Lamk.) Based on The Woven Fibres Orientation and Thickness of Layers
The research presented is a study of acoustical characteristics of agel fibre. This study aimed to determine the effect of variations in thickness and orientation of agel fibre to its absorption coefficient (α).
Woven sheet of agel fibre with size of 3×1 m2 was used in this study. Sheets varies in its woven direction. This research used woven agel fibres by varying the thickness and the fiber orientation. Variations of thickness were with a single and double layer. As for variation of the woven orientation, sheets of double layer were stacked parallel and crossed. Testing was conducted in a Reverberation Chamber at frequency f 250 Hz, 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz.
