Summary:We analyzed the acoustic spectrum of Bahaba taipingensis by monitoring its sound with passive acoustic method to provide basic data for the non-destructive investigation method, underwater noise environment analysis and sounding behavior of B. taipingensis. We carried out acoustic monitoring on 96 individuals of B. taipingensis by microMARS acoustic recorder in the indoor aquarrium and the two outdoor pools of Dongguan B. taipingensis Nature Reserve from March to May in 2017(two periods and each period had 7 days and nights). We had monitored 246 sounds in total, belonging to seven types(drum sound, humming sound,cracking sound, clacking sound, bird sound, cha goo sound and other sounds). No significant difference was observed in the number of sounds between day and night. The drum sound was the main sound of B. taipingensis(175 times). The drum sound was composed of 1-3 pulses, being dominated by a single pulse type of drum(139 times). The drum sound had some sine shaped waveform(energy: 0-1 000 Hz), and its
