抜粋

When a high-speed train enters a tunnel, a pressure wave is generated in front of the train. This pressure wave propagates to the tunnel exit and spouts as an impulsive wave, which causes a bursting sound. It is important to estimate the waveform of the compression wave at the tunnel exit. In this paper we have experimentally studied the transformation of the propagating compression wave in a high-speed train tunnel simulator. The criterion for whether the wavefront steeps or spreads is discussed using the acoustic Reynolds number and the Burger's equations.
