Assessment of micro-pressure wave emissions from high-speed railway tunnels

Last updated on 20 December 2012 4:22

When a high-speed train enters a tunnel a compression wave is generated which travels through the tunnel and results under certain conditions in the emission of a so called micro-pressure wave at the opposite portal. Those micro-pressure wave emissions can cause strong acoustic noise which may contradict to an environmentally...
