A method of reducing acoustic noise produced by a hybrid power plant having a thermal engine and an electrical motor, the method includes: driving a propulsor with the hybrid power plant operated at an initial work split ratio and at a power level; receiving a signal from one or more sensors, the signal indicative of an initial noise signature generated by the hybrid power plant operated at the initial work split ratio and the power level; determining that the initial noise signature generated by the hybrid power plant is above a target noise signature of the hybrid power plant; determining a work split ratio of the hybrid power plant which will generate a noise signature that is at or below the target noise signature; and operating the hybrid power plant at the work split ratio.
