| Summary, etc | Sound absorption is any means of reducing the sound pressure by converting its energy into hear within a material. The types of sound absorbing materials determine the frequency distribution of niose to be absorbed.Rubber composites as sound insulators were prepared by incorporation of two types of fillers, namely kenafe and calsium carbonate in blends of 50 mole;epoxidised natural rubber (ENR 50) and methyl methacrylate (MMA)- grafted natural rubber latex. A two microphone impedance tube was used to investigate the sound absorption coefficient value of the composites prepared. Rubber composites exhibited excellent sound absorption properties with sound absorption coefficient value of the composite. The presence of calcium carbonate that was scattered on the walls of voids had increased stiffness of the composite, providing better absorption of sound waves. |
