摘要：
Well-known advantages of cellular metals are their high ability for energy absorption. good damping behavior and sound absorption at a high specific stiffness. This paper has a focus on the absorption coefficient representing the acoustical property. The absorption coefficient is analysed experimentally by an impedance tube. Results fit well to theoretical investigations described by Champoux and Allard. (C) 2008 Elsevier B.V. All rights reserved.
