In this paper, in order to improve the interior sound field environment of high-speed train, preferably select the best roof structure material selection scheme, the roof structure of high-speed train is studied. Besides, sound insulation performance of the roof, internal noise of the passenger train and psychoacoustics are linked, which proposes the noise prediction and material selection method in high-speed train based on psychoacoustics. It helps to come to the following conclusions:Firstly, compared to the A-weighted sound level, the evaluation method of vehicle interior noise basing on the objective parameters of psychoacoustics can not only reflect the subjective feelings of the ear more reasonably but also preferably select the best roof structure material selection scheme. Secondly, when replacing the glass wool in the roof structure into rock wool, the structural weighted transmission loss will increase 1.3 dB, the total value of the interior SPL will be deteriorated, while loudness and noisiness be increased 1~1.5 sone and 1~2 Noy. Thirdly, when adjusting the 5 mm sound insulation pad to one side of the train, the structural weighted transmission loss will increase 1.4 dB, the total value of the interior SPL will be unchanged, while the loudness and noisiness be increased 3~5 sone and 2~3 Noy. The research and evaluation methods in the paper are practicable and significant for the noise prediction and material selection of high-speed train definitely.
