• When a train enters a tunnel at high speed, an impulsive pressure wave, called a micro-pressure wave, is radiated from a tunnel exit portal. Because it is one of the important wayside environmental problems in high-speed railways, many studies about its countermeasures have been conducted. The principal countermeasure applied to the Shinkansen on the ground side is a tunnel entrance hood. In this paper, a new countermeasure to install a tunnel exit hood to reduce the micro-pressure wave has been proposed. The tunnel exit hood has an inside partition which divides the inside of the hood into two parts in the vicinity of its mouth with the end of one part closed. It has been shown that the tunnel exit hood can be effective in reducing the magnitude of the micro-pressure wave.
