Abstract     [Buy Article]
    This study is intended to assess low frequency sound radiated from a viaduct under normal traffic. The bridge comprises steel box girders and wide cantilever decks on which vehicles pass. The low frequency sound and the acceleration response of the bridge under normal traffic are measured to investigate how bridge vibrations affect the low frequency sound observed near the bridge. Observations demonstrate that strong relationships exist between frequency characteristic of bridge
 
Key Words
    field experiment; low frequency sound; sound pressure level; steel box girder bridge; traffic-induced vibration.
