Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The sound absorption property of a multilayered aluminum foam structure was investigated at present work. The absorption coefficients of the structure were measured by the transfer function method. Based on the equivalent fluid model, a theoretical model for the multilayered structure was presented. Compared with the experiment, the theoretical sound absorption coefficients of the multilayered structure were consistent with experimental values. The theoretical model is suitable for evaluating the sound absorption characteristics of the multilayered structure. Furthermore, the experiment and theory show the multilayered structure has an excellent absorption characteristic because of its series multi-resonance structure. And the best acoustic absorption characteristic of the multilayered Al foam structure can be obtained by adjusting the structural parameters.
