Abstract: Aerodynamic noise reduction control is very important for environmental protection and passage comfort of high-speed train (HST). According to the 1:8 scale model of a 400 km·h^-1 high-speed train, six aerodynamic noise reduction control methods based on three control types of bogie section, front edge, side edge and rear edge, are established. The sources of unsteady flow field and aerodynamic noise are obtained by large eddy simulation (LES). The far-field and near-field noise calculation methods of FW-H equation and acoustic perturbation equation are used to obtain HST aerodynamic noise. The aerodynamic noise reduction and frequency ranges of different control methods are obtained for far-field and near-field noise. Compared with the wind tunnel test, the total sound pressure level deviations for 90% of the 30 far-field measurement points are within 3 dB(A), the trend of spectrum change is the same and the magnitude difference is small. At 400 km·h^-1, different noise reduction control methods reduce the average sound pressure level at far-field measurement points by 1.4 dB(A), the turbulent fluctuation power level of bogie section by 3.4 dB(A), and the sound power level of bogie section by 0.6 dB(A). Thickening the straight wall and the cowcatcher in the front edge control, increasing the height of side cover in the side edge control and chamfering in the rear edge control can all reduce the far-field noise level and the turbulent fluctuating pressure level on the roof surface of bogie section. The sound power level in the bogie section can be reduced by thickening the cowcatcher and chamfering the rear edge, however, reducing the volume of bogie section and enclosing the section will increase the sound power level in bogie section.
