| 摘 要： | 为确定居住区内临近车库出入口建筑噪声防护距离,将行驶车辆看作半自由空间中辐射的点声源,在考虑车库出入口及区内道路车流噪声的基础上,建立了临近车库出入口建筑正立面噪声理论计算模式.通过实测,对模式进行了修正,模式的预测值与实测值误差在±1.5dB之内.

| Abstract: | To ascertain the noise defending distance of the building near the entrance or exit of the garage in residential areas, the running vehicle is regarded as a point source of noise radiated in half-infinity space. On the basis of considering the noise of running vehicles at the entrance or exit of garage and in the area, a theoretical computing model of the noise field of the building near the entrance or exit of garage is established. The model is amended through practical measures. The error between the practical value and the prediction value of the model is less than 1.5dB. |
