摘　　要：多孔材料是在声频工程中最常用的吸声材料,以吸收中高频为主。分析了离心玻璃棉板、环保有机吸声棉、纤维织物、皮革、玻璃纤维、海绵、木丝板等多孔材料的吸声特点,说明了影响多孔材料吸声性能的多种因素,明确了多孔吸声材料与构造的应用场合与要求。Porous materials are the most commonly used sound-absorbing materials in audio engineering,which mainly absorb medium and high frequencies. This paper analyses the sound absorption characteristics of porous materials such as centrifugal glass wool board,environmentally organic sound absorption cotton,fiber fabric,leather,glass fiber,sponge,wood wool board and so on,describes various factors affecting the sound absorption properties of porous materials,clarifies the application occasions and requirements of porous sound-absorbing materials and structures.
