The Effect of Compression on Sound Absorption of Multi-layered Isotropic and Transversely Isotropic Porous Materials at Oblique Incidence
Abstract: Porous materials which are effective in sound absorption in automobile and airplane industry areoften used under compression. This compression is associated with a reduction in thickness and theresulting changes in acoustical properties and non-acoustical parameters of the porous materials.Therefore, these acoustics changes should be taken into account when the behavior of these materialsis studied. So far, the studies on the effect of compression on sound absorption characteristics ofporous materials have …
