摘要：

The acoustic properties of three kinds of polymeric micro-particle materials have been investigated. Based on it, a novel sound absorption material with multi-layered structure has been fabricated by using polymeric micro-particles with low reflection as matching layer and high sound absorption one as sound energy attenuation layer. To optimize the absorption characters in demanded frequency regions, a double impedance matching layers have been created. The experimental results show that the particle materials fabricated by the principle of impedance matching processes excellent sound absorption character in wide frequency regions.
