Study on Automatic Monitoring of Sound Environment in Xiangyang City
The existing manual monitoring sites were investigated and monitored and the automatic monitoring sites were selected through the acoustic environment function area survey monitoring method.The 16 existing manual monitoring sites in Xiangyang City were investigated on the spot to determine whether they were in line with the principle of location layout.The sound environment functional area was investigated and monitored,and the rational construction of acoustic environment automatic monitoring stations was realized based on the results.The relative deviation of the average equivalent sound level between the automatic and manual measuring points was 0.38%～1.71%,and the data continuity of the auto m atic m easuring points was good.The auto m atic m onito-ring point is at the height of 1.2 m and 5.0 m,and the co m parison m onitoring is carried out.After the height of the m easuring point is increased,the measurement value change of the same measuring point is less than 3.0 dB,so 5.0 m is m ore appropriate for the auto m atic m onitoring station.
