Abstract
Porous materials currently used in the building industry require to have a high performance in terms of sound insulation and absorption. In reality, each material is characterized differently for each application, focusing on the properties important for each matter. This has led to having a nonuniform collection of data for each material. In this paper the information collected from the available literature has been arranged to suit a finite element model of porous materials, with the purpose of analysing the absorption coefficient and other acoustical behaviours of the materials. By considering the reported properties, plus estimating the missing not-characterized values, the model is completed, and results are compared between porous materials.
