摘　　要：分析了各类功能区噪声的特点,提出自动监测点位布设的基本原则。对传声器水平距离和垂直高度的确定做了相关比对实验,结果表明,传声器水平距离选择距反射面不小于3 m,垂直高度为4～5m时,能较好地反映该功能区受环境噪声影响状况。Analysed the characteristics of noises in various functional districts. Some basic principles on spot location were put forward. Some experiments were carried out on the determination of distance and vertical height for microphone. It showed that when the reflector horizontal distance is no less than 3 m away from the microphone and the vertical height is about 4 - 5 m, the status of environmental noise in the functional districts can be better reflected.
