Some typical entrances/exits of the underground garages are chosen in urban residential areas. On the basis of the optimization of the positions of the noise sampling points and the groupings of the synchronous sampling points, by means of the acoustical analysis of the noise samples, the relation of the correlative factors, among the ramps' noise of the entrances or exits of the garages, the structure, grade, shape of the ramps, upgrade and downgrade, is studied. The prediction model of the ramp's noise influence of the entrance or exit of the garage is established through amending the noise influence of the entrance or exit of the even concrete road.
在城市居民区选取了一些典型的地下车库出入口。在优化噪声采样点位置及同步采样点分组的基础上，通过对噪声样本进行声学分析，研究了车库出入口坡道噪声、坡道结构、坡度、形状、上下坡等相关因素之间的关系。通过修正平坦混凝土道路出入口的噪声影响，建立了车库出入口坡道噪声影响预测模型。
