2 Literature Review 2.1 Porous Materials For the purposes of this report, porous materials is defined as a medium containing voids[2]. The skeletal material is called the matrix and the voids are filled with a fluid (usually air). The physical properties of the materials can be characterised by bulk, macroscopic and microscopic properties. Most of which have an impact on the acoustical performance of the material. Sound energy is lost in porous materials when it is transformed into heat. This is…
