摘　　要：针对城市居住区2种典型的建筑布局,结合随机点声源模型,对居住区内地下车库噪声影响进行了分析计算.通过实测值和预测值的比较,该预测模型精度较好.运用该模型预测规划与新建的居住区地下车库的噪声的影响,可为城市小区建设规划中有效控制噪声污染提供科学依据.Aimed at certain types Of building dispositions in urban residential region, the noise impacts of the underground garage is analyzed and calculated with the simulation model of random point sound source. The comparison between the predicted results and measured value of noise level shows that the predicted model presents an acceptable degree of accuracy. Adopting this model to predict noise impacts of the underground garage in designed and newly-built residential region will provide scientific basis for effective noise control.
