| Abstract: | The noise characteristics of Shanghai rail transit Line 3 is analyzed, including the time progress of A-weighted sound level, the spectrum of A-weighted sound level, the time-frequency analysis, the spectrum of vibro-acceleration on the bridge and rail analysis, the acoustic source identification, as well as the co ntribution analysis of the main sources to the overall noise near the elevated r ail. This paper can provide reference for the vibration and noise reduction in b oth Line 3 and other urban rail transit lines. |
