Zusammenfassung:	The invention discloses a water turbine operation noise extraction method and terminal, and the method comprises the steps: determining a first target noise attenuation coefficient corresponding to a first real-time power generation flow and a second real-time power generation flow according to a first relation curve, a second target noise attenuation coefficient corresponding to the first real-time power generation flow and the second real-time power generation flow is determined according to the second relation curve, and the operation noise sound intensity of the first hydraulic turbine set is obtained according to the first real-time noise sound intensity, the second real-time noise sound intensity, the first target noise attenuation coefficient and the second target noise attenuation coefficient. The operation noise intensity of the first hydraulic turbine set in the first real-time noise intensity can be accurately separated only through the easily collected set noise intensity and the power generation
