Background Noise of the Project Site of Comparison Base of Wuhan Seismic Station
Abstract The background noise level and power spectral density of the comparison base of Wuhan seismic station are calculated, and the root mean square (RMS) value of noise in the range of 1-20 Hz is given. According to the calculation results and in accordance with the Technical Requirements for the Observation Environment of Seismic Stations, the background noise of the comparison base of the Wuhan seismic station was rated, and the reasons for the change of the background noise of the comparison base of the Wuhan seismic station with time were analyzed, and optimization suggestions were put forward. The background noise level of the station comparison base is low, and the site environment is suitable for the instrument comparison measurement.
Key words :
Wuhan seismic station
earthquake background noise
power spectral density
noise level of comparison base
