N2 - The railway system in Korea is developing more and more rapidly. After development the next generation hi-speed train(HEMU-430X), Korea will can compete against developed country. But, speed increasing will cause the greater rolling and aero dynamic noise. In this study shows that measurement noise of the KTX train by 300kn/h class, and KTX- Saneheon(KTX- II) train by 350kni/h class. The measurements are carried out on open area and noise protection barrier installed area. The microphones were placed at a distance of 3m from the center line of the track at a height of 0.5m above the upper surface of the rail and at a distance of 7.5m from the center line of the track at a height of each 0.6m above(.\lax 4.2m) the upper surface of the rail. One microphone was placed at a distance of 25m for check the environmental noise. And to know the possibility of noise absorbing block, this study shows the FEM analysis about wind pressure in running status.
