Reflections of plane waves from the open ends (portals) of axisymmetric pipes and plane two-dimensional (2-D) channels are investigated analytically, numerically and experimentally. An analytical approach developed by Rudinger [1] for pressure decay at an axisymmetric, flanged portal is extended to

When a high-speed train enters a tunnel, it generates a compression wave which propagates along the tunnel ahead of the train. A small proportion of the wave subsequently emerges from the exit portal of the tunnel as an impulsive wave. This so-called micro-pressure wave causes annoyance through low
