| Abstract: | The interior noise levels were measured for the existing line first-class vehicle passenger compartment in running. Using the analysis methods including 3tdoctave, 3rdoctave vs.t, FTT vs. t, Ievel vs. t and FFT analysis, analyze the characteristics of the interior noise of the vehicle running different lines (e. g. a tunnel, a bridge or a ramp) to table the proposals for noise reduction and to improve the structure and materials of the vehicle body and reduce the interior noise of vehicles. |
