When a Shinkansen train passes through a tunnel, the pressure change due to the pressure wave in the tunnel penetrates the cars. This gives rise to aural discomfort of passengers, which becomes severe when trains pass each other in the tunnel. In this paper, a new ventilation system for alleviating this aural discomfort is described. A method of numerical simulation of the pressure change outside and inside of the train is also presented. A field test to confirm the fundamental performance of the system has been carried out using Shinkansen electric cars Series 300 and the results are compared with those of the numerical simulation. Moreover, the applicability of the system to a super-high-speed train travelling at 350 km/h is ascertained by numerical simulation.
