3.2. Oil Palm Trunk Because they are more sustainable and can be replenished, natural fibers are increas- ingly being used to replace synthetics in sound-absorbing materials. Research on oil palm trunk (OPT) fiber's SAC as an acoustic material is presented here. All OPT specimens were ...
The acoustical properties of porous, synthetic and natural fiber materials can be used to attenuate the unwanted sound energy. The most important issue to control the noise by using passive methods is the size of the absorbing materials. Various factors such as type of the material, its ...
Owing to three dimensionally dispersed fiber structure, ultralightweight, high porosity, the sound absorption coefficient of ULW-CFM with silicasol reached 0.65 above 5000 Hz. Results show that ULW-CFM modified by silicasol has a promising application as a degradable sound absorbing material for ...
