Floating slab track is a quality-spring vibration isolation system, which is the most effective ways to reduce the ground vibration and noise transmission. However it has other disadvantages, such as there is low frequency noise problem like "gu long gu long" in the carriage when the train runs across steel floating slab track (FST) area. According to this phenomenon, this paper compared the two different bearing floating slab noise data, studied their dynamic characteristics under train loads. From the isolation principle and noise radiation theory, explained the reasons causing the phenomenon and put forward relevant suggestions.
