"Sound-absorbing material"(吸聲材料)是指通過物理結構特性将聲能轉化為熱能或其他形式能量,從而減少聲波反射的工程材料。這類材料在建築聲學、工業降噪和音頻設備領域具有重要應用。
定義與原理 根據美國聲學學會(Acoustical Society of America)的定義,吸聲材料的核心功能是降低聲波在空間内的混響時間。其工作原理主要基于多孔結構中的空氣粘滞阻力效應和材料内部纖維的振動摩擦損耗,符合國際标準化組織ISO 354标準中關于聲學材料性能的測定方法。
材料分類
性能指标 主要依據ISO 11654标準中的吸聲系數(NRC值)分級體系,優質吸聲材料的NRC值可達0.9-1.0範圍。美國聯邦規範HH-I-197D對材料防火性能提出明确要求,需同時滿足ASTM E84防火測試标準。
應用場景 包括錄音室聲學處理(符合ITU-R BS.1116标準)、辦公室開放式空間降噪,以及交通領域的高速公路聲屏障(符合FHWA噪聲控制規範)。德國弗勞恩霍夫建築物理研究所的實證研究表明,合理使用吸聲材料可使室内語言清晰度提升40%以上。
