The structure model of parallel microperforated panels (MPP) with different resonance frequencies has been studied in the paper, and the combination absorption coefficient is also calculated. The calculation results of absorption coefficient have been contrast with the experiment results, which come from the existed experiment results and simulation experiments by the SYSNOISE software according to the GB/T 18696. The experiment result indicates that the calculation method of the acoustic impedance ratio and the combination coefficient of the parallel MPP in the paper is credible.
