Abstract
Increasing popularity of acoustic absorbing metamaterials is followed by the problem of defining the performance of the unit cells used for the further development of the structures. The review of the state-of-the-art solutions revealed problems in the replication of the common designs and the attempt to replicate some of the designs showed great dispersion in the received results compared to the references. Typically, the reference papers do not provide detailed information on the modeling, which may be the reason for the encountered problems. The paper will present the numerical modeling results in COMSOL Multiphysics for the essential metamaterial unit cells comparison of the sound absorption coefficients – the slits, Helmholtz resonators series, or quarter-wavelength resonators. The different modeling techniques, physics application, and mesh sensitivity influence will be investigated. The paper will discuss the results and the advantages of using the given FEM strategy with a comparison with the impedance tube measurement results performed for the validation of the numerical models.
