This study intends to confirm the potential of bamboo twigs as an alternative sound absorbing material in acoustic applications. The pieces of bamboo twigs are arranged according to their edges: hollow edges (RR) and node edges (BB), creating five upper-bottom surface combination patterns. The acoustical characteristics were examined through absorption coefficient (α) and standard deviation measurements. The result shows the best surfaces combination is the RB-RR specimen. RB-RR specimen is a combination of hollow and node edges on the upper surface and hollow edges on the bottom surface. Although narrower in frequency ranges, the specimen performs approximately equivalent to the well-known Glass wool in terms of maximum absorption coefficients (α). Refers to the measurement results, the abundant bamboo twigs can be qualified as a potential alternative for sound absorption material in the future. ## Keywords - Bamboo - Materials science - Absorption (acoustics) - Node (physics) - Surface (topology) - Noise reduction coefficient - Composite material - Relative standard deviation - Acoustics - Geometry - Mathematics - Physics - Statistics - Porosity - Detection limit --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
