The present invention relates to an apparatus for reducing tunnel micro pressure waves generated when a high-speed train enters a tunnel. Air inside the tunnel is moved toward the speed direction of the train to reduce the impact generated when the train, which enters the tunnel at high speed, collides with the air inside the tunnel. Therefore, the relative speed with the train is reduced, and the strength of shock waves, which are generated when the high-speed train enters the tunnel, is dramatically reduced. Generation of noise due to micro pressure waves is reduced, and the pressure inside a cabin is increased. Therefore, generation of unpleasant to the ear is minimized. When the method and the apparatus for reducing tunnel micro pressure waves are applicable to the high-speed train which approaches the speed of sound, strong micro pressure waves are not generated in spite of the fast speed. |
