| Abstract: | In this paper, the effect on nonlinear acoustic characteristics of microperforated plate absorbing structure has been studied experimentally under the condition of intensive sound pressure and high Mach number. It is shown that the attenuation coefficient will decrease obviously with the increase of Mach number, and the nonlinear acoustic resistance and acoustic mass will reduce slightly. Furthermore the resonance peak of the structure will move, and the Doppler effect of sound transmission in high speed flow must be considered carefully when a structure is designed. |
