摘要
噪声污染对人类身心健康的不利影响日益增加,而且制约经济发展。怎样有效的降低噪声成为人类面临的一大重要课题,寻找降噪性能优异的吸声材料便是其中一个解决方案。本文阐述了吸声材料在降低噪声方面的重要意义,并介绍了吸声材料的分类。分别介绍了多孔吸声材料、共振吸声材料的吸声原理及实际应用,以及吸声材料的吸声性能的评价和影响因素。重点介绍了纤维类吸声材料和泡沫类吸声材料的分类、发展史、研究进展;有机纤维吸声材料、无机纤维吸声材料、金属纤维吸声材料吸声性能的优缺点;并对多孔吸声材料的研究发展趋势加以展望。
The negative impact of the noise pollution on human health of body and mind is increasing,and restricted economic development.How to effectively reduce the noise becomes an important topic for the human.It is one of solutions to look for noise reduction by sound absorption materials.This paper introduces classification of sound-absorbing material and its importance.The resonance sound absorption materials and porous sound absorbing materials are introduced in principle and practical application.And this paper introduces the acoustical absorption material and to evaluate the performance of the influence factors of sound absorption performance of porous sound absorbing material.We emphasize on classification,development history and research progress of fiber sound-absorbing material and bubble absorption material,and advantages and disadvantages of the sound absorption performance of fiber sound-absorbing material made by organic fiber,inorganic fiber and metal material.And we look forward to the trend of research and development of porous sound absorbing material.
