This study focuses on developing an analysis model to assess the bridge vibration noise caused by vehicles traveling over a girder bridge. For this purpose, a bridge model and a moving vehicle model are used. The dynamic behavior of the bridge is rationally analyzed by studying the interactions between the bridge and the vehicle. To study the sound pressure level of the vibrating bridge caused by vehicles traveling over it, the sound pressure analysis program is developed. This program is used to analyze the sound pressure level on the vibrating surface and the sound pressure level radiating off the surface by calculating the vibration velocity of the bridge's surface with plate elements and the integral formulation of Kirchhoff-Helmholtz. Finally, a parameter study is conducted. Using random functions, a vehicle noise model is used to determine the traffic noise and the vehicle noise and to show how the bridge vibration noise affects the overall noise.
