The results of experimental studies of the influence of the geometrical dimensions of heavy-concrete articles on the parameters of the electric response under an elastic impact excitation are presented. It is established that an increase in the length of models at a constant cross section leads to a decrease in the electrical-response magnitude and an increase in the signal attenuation factor, as well as to a shift of the main spectral maximum of electrical signals toward lower frequencies and a change in the positions and ration of significant spectral peaks. It is shown that changes in the geometric dimensions of heavy-concrete articles do not lead to appreciable changes in the maximum cross-correlation coefficient between the electrical-response spectrum and the spectrum of freely damped harmonic oscillations.
