摘　　要：在道路交通噪声随机点声源预测的研究基础上 ,根据地下停车库车辆进出的特点 ,提出分时段建立的不同车辆类型的随机点声源模型 .该模型通过计算机模拟给出按时段分布的预测值 ,与实测值进行比较后发现 ,模型预测精度较好 。On the base of research about prediction of road random model of point noise source and according to the quality of the vehicle efflux and inflow,the authors brought out a model of noise source about different kinds of vehicle, which were set by divided time.Through computer simulation, the comparison between value of prediction and actuality indicated that the precision of model was good, and was agree with actual states.
