REDUCTION OF MICRO-PRESSURE WAVE RADIATED FROM TUNNEL EXIT BY HOOD AT TUNNEL ENTRANCE

An explosive noise produced by high-speed trains emerging from long tunnels laid with concrete slab track has proved objectionable. Hoods were installed at the ends of one tunnel to reduce the micro-pressure wave preceding trains. A standardized hood, developed by model tests, is to be installed on existing and extended lines of the Shinkansen.
