In recent years, a number of models to calculate the acoustical behaviour of porous materials (sound absorption, sound insulation and vibration damping) have been developed [1]. Although these models are based on physical sound theories, they require a number of material parameters and the output of a calculation will depend on the accuracy of the input parameters. Depending on the complexity of the porous material and the configuration to be modeled, up to seven parameters may be needed.
