【Abstract】The Doppler effct exists during the driving process of vehicles.However，in the currently established trafic noisepredictionmodels，theinfluence of theDopplereffectofvehicledriving noiseontraffcnoiseisrarely considered.Byestablishinganoiseradiationmodelofsingle-vehicledrivingandusing thetheoreticalcalculationof MATLAB software，the influence degree of vehicle speedandthe positionof the receiving point on traffc noiseunder the Doppler efct is analyzed.The results show that when the vehicle speed is less than 67.0km/h ，theinfluence of the Doppler effect on traffic noise is less than 1.OdB.When the vehicle speed is greater than 67.0km/h ，the influence range of the Doppler effect on traffic noise is1 to 3dB.
