Description This research was conducted to determine the sound attenuation level of  composite. The composite used in this study iscompound Kalimantan sawdust and pineapple leaf fiber. The research objective was to determine the damping rate of composites (fine Kalimantan sawdust and compound of coarse Kalimantan sawdust with pineapple leaf fiber), so it can be used as an alternative sound absorbent material. The composite testing process uses a Sounds Level Meter by adjusting the frequency of the sound source. The space partition is a composite, measured the value of sound intensity at a certain distance, then given a partition, the sound intensity is again measured with the same distance. The results of the absorption coefficient of pineapple leaf fiber composite and red meranti wood sawdust can be used as an alternative sound absorbing material besides glass wool so that it can minimize side effects for public health. ©2018 JNSMR UIN Walisongo.
