- W2381978081 abstract "The sound barrier design has become a major theme concerned by international academic circles.Setting sound barriers on both sides of railroad track is an effective and economic method for railway's noise control.The diffraction attenuation calculation is the kernel content of the sound barrier design,and the equivalent frequency of the sound barrier is one of the important parameters for the diffraction attenuation calculation.In order to raise the efficiency of sound barrier design,the noise frequency characteristics of freight trains in different locomotive traction and at different operating speed are studied by testing.Meanwhile,the sound barrier equivalent frequencies of freight trains under different working conditions are obtained by statistical analysis of the measured field data." @default.
