Porous materials are used for noise treatments. Biot's parameters such as porosity, air flow resistivity, tortuosity and stiffness characterize the behavior of porous materials and are major factors to control the acoustic performance inside vehicles. In this paper, experiments of Biot's parameters and acoustic performance are conducted to find the relation between the acoustical material properties and their performance for various absorbent materials. Response surface model (RSM) are used to build up a database to find that relations and sensitivity analysis are conducted. The influence of Biot's parameters for the performance in the frequency domain is evaluated.
