| Resumo: | The analytical simulated results have been done using Matlab simulations. The numerical results have been obtained using Comsol Multiphysics. The schemas and photos have been based on the micro-capillary samples and the experimental set-up. Measurements were performed on a small impedance tube installed vertically in a semi-anechoic environment. A loudspeaker, connected at the base of the tube, generates a random pressure field that propagates towards the sample holder for the determination of the absorption coefficient. A complete description is provided in the corresponding publication. |
