One of the mental and physical discomfort due to traffic vibrations generated by highway bridges is low-frequency sound. The maximum value of this low frequency sound in the 10 - 20 Hz band, is obtained immediately after a heavy vehicle passes in the vicinity of an expansion joint. The authors have analyzed the vibration measurement record of the vehicles and the bridges. It was then confirmed that the road roughness in the vicinity of the expansion joint causes the resonance of the vehicles and the bridge, and generates low-frequency sound in the 10 - 20 Hz band. Furthermore, a numerical analysis was carried out considering the road roughness in the vicinity of the expansion joints to determine the adverse factor on low-frequency sound.
