A method for determining a probe signal for acoustically interrogating an electrochemical system, the method including transmitting a first signal, called the calibration signal, including a wave train of multiple frequencies, the spectral density associated with each frequency being identical; receiving the response of the electrochemical system to the calibration signal; determining, on the basis of the received response and for each frequency of the calibration signal, a signal attenuation factor; determining, for each attenuation factor, a correction factor according to the attenuation factor so as to associate a correction factor with each frequency of the calibration signal; and determining the probe signal, the probe signal being obtained by multiplying the spectral density associated with each frequency of the calibration signal by the correction factor corresponding to the frequency in question.
