FIELD: physics.
SUBSTANCE: method includes additionally determining mechanical displacement of the working surface of the investigated seismoacoustic sensor using a contactless method; simultaneously determining the first zero of the function of the envelope of the spectral power density of the electrical signal at the output of the investigated seismoacoustic sensor; comparing the signal proportional to the mechanical displacement of the working surface of the investigated seismoacoustic sensor and the signal from the output of the investigated seismoacoustic sensor; judging the dynamic characteristics of the investigated seismoacoustic sensor based on the comparison results.
EFFECT: higher reliability of monitoring.
