A method for processing an electrical signal for an acoustic emission system. The method carried out by the system includes the following steps: a) transmitting a calibration signal to the electroacoustic transducer; b) emitting a sound based on the calibration signal, by the electroacoustic transducer; c) measuring the voltage across the terminals of the load; d) calculating the variation in impedances of the electroacoustic transducer as a function of the variation in frequencies of the calibration signal; e) determining the resonant frequency of the electroacoustic transducer from the variation in calculated impedances; f) selecting a set of acoustic filters in the database based on the determined resonant frequency; and g) applying the set of acoustic filters to the electrical signal in order to process the electrical signal coming from the input.
