Environment effects due to traffic transmit is paid more and more attention nowadays. In suit experiment is one primary approach to this problem, but because of mass background vibration, the testing data can not represent the vibration characteristic of source and promulgation. In order to obtain ideal data, two methods to remove background vibration were presented in this paper, one was Fourier Amplitude Revised Method, the other was Acceleration Vibration Level Revised Method, the two methods were tested in measured data, the result showed that the two methods were effective. Basic principles to banish background vibration were discussed in the end.
