摘要
简要地介绍了吸声材料的基本特点，阐述了无纤维性吸声材料（特别是微穿孔板吸声结构）取代传统的纤维性吸声材料的可能性及其重要意义，较详细地介绍了近年来德国以及我国科研人员在无纤维吸声材料研究上所取得的进展．
The essential characteristics of sound absorption materials are briefly reviewed.The possibility and the significance of replacing fibred absorption materials by fibreless materials,especially by microperforated panels,are discussed.Recent developments in this area both in Germany and China,are discussed in detail.
