Reduction in aerodynamic noise emitted from a pantograph is an important subject for environmental preservation and speed-up of Shinkansen trains. In this study, an effect of pantograph horns to the aerodynamic noise characteristics was investigated. As a result, it is clarified that the pantograph horns affect aerodynamic noise properties significantly and shape improvement around the joint area of the pantograph head and the horns is an important factor for the reduction of aerodynamic noise.
