AbstractIn recent years， multiple unidentified sounds have been heard in the Tongling area，and significant vibrations have ben felt withinstructures.Toconduct a time-frequency analysisof these unidentified sounds，this study used the time-frequency analysis method in the seismic event recognition system （SERS） developed by the Non-Natural EarthquakeResearch Laboratoryof the Instituteof Geophysics，China Earthquake Administration.Throughusing the SERS，a comparative analysis of time-frequency dataand waveform characteristics was conducted between unidentified sound and natural earthquakes，mine explosions，anda chemical plant explosion event in the Tongling area. It was preliminarilydeterminedthattheunidentified soundoriginated fromthe groundorabove.Fieldvisitsand investigations showed that when the unidentified sound occurred， no explosions，geological disasters，or other safety production accidents were observed in thecity.Itwas thusconcludedthattheunidentified soundeventwas causedby human activity on the ground （or surface）.This study provides a reference for using SERS to analyze the source of other non-natural earthquakes.
