The sound absorption properties of materials improve with the increasing the ratio of porocity. The surface modification to the waste rice was carried out by using sodium hydroxide via conventional method. Finally the sound absorption properties of the rice husk/polyurethane composite with low and high sound frequency were investigated.eninfo:eu-repo/semantics/openAccessSound AbsorptionWaste Rice/Polyurethane CompositesSurface ModificationsConference Object
