The generating mechanism of bridge structure-borne noise, the spectral characteristics of structure noise and the relation between structure noise and train speed and the influence factors of bridge radiation efficiency are introduced. In the paper, plural calculation methods and the present progress are briefly introduced.The defects of each method are pointed out. Strategies for reducing the bridge structure noise are include vibration reduction/isolation, vibration transmission/limitation and energy attenuation. The problems of reducing the structure-borne noise are pointed out for further studies.
