摘要
利用吸声材料来吸声降噪是治理噪声污染的重要途径之一。阐述了共振吸声材料与多孔吸声材料吸声降噪的机理,较为详细的介绍了各种吸声材料的分类、研究与应用及性能评价,对吸声材料未来研究发展趋势加以展望。
It is an important way with the sound - absorbing materials to improve the sound pollution. The sound absorbing mechanism was reviewed for the resonant sound - absorbing material and porous sound - absorbing material. The types, research, applications and performance evaluation for all kinds of sound - absorbing were introduced in detail. The trend of development for the sound - absorbing materials was reviewed.
