| Abstract: | The digital records of the noise background are selected from 11 substations in the Urumqi Digital Telemetered Seismic Network, and the RMS (root-mean-square value of ground surface motion noise), effective dynamic surveying range and noise power spectrum are analyzed and calculated. The frequency bands at every sub-station in which the background noise is relatively concentrated are determined. |
