Abstract

Bamboo is mostly used in the architectural and room interior scope as additional material for room aesthetics. Handicrafts that are often used for this scope are woven bamboo in the form of sheets or board. This study aims to determine the acoustic abilities of bamboo woven panels based on the absorption coefficient and transmission loss values. The specimens of this study are thick woven bamboo, thin woven bamboo, and a combination of the two materials mentioned before. The process of measuring the absorption coefficient refers to the ASTM C-432 method and for measuring transmission loss refers to the ASTM E-90 and ASTM 413 methods to calculate the sound transmission class. Based on the results obtained in this study, it is known that woven bamboo can absorb sound at frequencies of 1250Hz to 5000Hz. the largest absorption coefficient is 0.45 at 2500Hz frequency which is owned by thin woven bamboo stacked with thick woven bamboo. Woven bamboo can transmit sound which is quite high that is thin bamboo woven material which has the largest noise reduction value of 34dB at a 200Hz frequency and has the largest STC value that is STC 19
