when high-speed train passing through tunnel, the micro-pressure wave noise will be created at tunnel exit, which worsening the living environmental condition along the railway line. Building hood at tunnel entrance is an effective method for solving this problem. In this paper, using numeral simulation method, the efficiency of single opening tunnel hood relieving micro-pressure wave noise was researched, the sensitive of hood opening parameter, such as opening ratio, ratio of length and width, was analyzed. In the end, the tunnel hood optimizing parameters was drawn out, which will play an important guiding role for high-speed railway tunnel hood design.
