Summary:Porous media are widely known in the areas concerning noise absorption and interior and exterior acoustics. One of the well known numerical techniques to simulate a porous layer is finite element method for which commercial software are available and are up to date according to the most common models to predict the properties of absorber materials. In this work, an investigation is done using a simple no-flow academic problem. By variating material pore complexity and properties, chosen models are studied to enhance the understanding of the various treatments.
