SoundPLAN在交通噪声对住宅小区影响评价中的应用

Application of SoundPLAN in Impact Assessment of Traffic Noise on the Residential Area

采用实测法对小区内的代表性点位进行噪声监测,并记录主要道路的车流量,将实测的车流量及道路相关参数输入到SoundPLAN预测软件中进行预测,计算预测值与实测值的差值。结果表明,偏差在2.8 dB(A)以内说明该软件可以用于交通噪声对住宅小区的噪声影响预测。用SoundPLAN预测软件绘制了住宅小区的平面和横截面声等值线图,形象的表达了交通噪声对住宅小区的影响。

Monitoring the noise of representative points in a residential areas and making records of traffic volume of the main roads, this paper input the parameters to SoundPLAN software to predict and compare the prediction value with the monitoring values. The results show that the deviation is within 2.8 dB（A）,which proved the SoundPLAN software can be used to calculate the impact of traffic noise to residential areas. Acoustic contour map is drawn with SoundPLAN software, which can eloquent show the impact of traffic noise to residential areas.
