Simulation for the sound absorption of micro perforated panels with metal fibers using finite element method

LI Chenxi;HU Ying;HE Liyan;Comac Shanghai Aircraft Design and Research Institute;  
To broaden the sound absorption bandwidth of micro perforated panels(MPPs), the finite element models for the acoustic properties of an MPP without and with inserted metal fibers are conducted in this paper.Based on the FEA models the sound absorption coefficients, the acoustic impedances, and the distributions of the particle velocity in a perforation were investigated. These models are validated by the measured sound absorption coefficients of an MPP without and with metal fibers. The simulated and measured sound absorption coefficients agree with each other. It is also found that the metal fiber insertion is able to broaden the sound absorption bandwidth due to the increased acoustic resistance resulted from the increased viscosity. This paper indicates that the FEA modeling can be used to simulate the acoustic properties of MPPs with complex structures. It can illustrate the effect of the complex structures on the acoustic properties of MPPs vividly and is worth of further research.
