In order to investigate the noise level of different line forms of 350 km/h high-speed train, the noise intensity at different distance from the Beijing-Tianjin Inter-City high-speed railway was tested and analyzed. The result indicates that the noise level radiated by the train reaches the highest at 60m distance. Then the noise level decreases with the distance increasing. The result is significant for noise reduction design of the express train-sets.
