When a high-speed railway train enters a tunnel, a compression wave is generated ahead of the train and propagates along the tunnel. This wave subsequently emerges from the exit portal of the tunnel as an impulse sound which may cause noise problems in the surrounding area. During the process of reflection and radiation, the flow at tunnel exit is very complex due to three-dimensional phenomena. The present paper studies the reflection process of a propagating compression wave from a tunnel exit and the generation mechanism of an impulse sound emitted from the tunnel exit. Three-dimensional numerical analysis is carried out for the discharge of a propagation compression wave from the tunnel exit with or without a side wall at the exit. The process of generating the impulse sound and the influence of the shape of tunnel exit are discussed
