Abstract

In the case of normal incidence, the acoustic performance of sound absorption coating is analyzed by using ANSYS software. The relationship between the damp item in the ANSYS code and the loss factor of material is obtained. The acoustic performances of sound absorption coating which contains periodically distributed cylindrical cavities are evaluated by both ANSYS code and two-dimensional analytic model, and good agreements show the applicability of ANSYS code. Furthermore, regarding the cell as a viscoelastic cylindrical tube is accurate enough in the two-dimensional analytic model.
