"Sound-absorbing material"(吸声材料)是指通过物理结构特性将声能转化为热能或其他形式能量,从而减少声波反射的工程材料。这类材料在建筑声学、工业降噪和音频设备领域具有重要应用。
定义与原理 根据美国声学学会(Acoustical Society of America)的定义,吸声材料的核心功能是降低声波在空间内的混响时间。其工作原理主要基于多孔结构中的空气粘滞阻力效应和材料内部纤维的振动摩擦损耗,符合国际标准化组织ISO 354标准中关于声学材料性能的测定方法。
材料分类
性能指标 主要依据ISO 11654标准中的吸声系数(NRC值)分级体系,优质吸声材料的NRC值可达0.9-1.0范围。美国联邦规范HH-I-197D对材料防火性能提出明确要求,需同时满足ASTM E84防火测试标准。
应用场景 包括录音室声学处理(符合ITU-R BS.1116标准)、办公室开放式空间降噪,以及交通领域的高速公路声屏障(符合FHWA噪声控制规范)。德国弗劳恩霍夫建筑物理研究所的实证研究表明,合理使用吸声材料可使室内语言清晰度提升40%以上。
