| Abstract: | The paper demonstrates that during triaxial loading of a core sample of dry sandstone, genetically related frequency ranges form in the waveguide, which are significantly spatially separated, but have a similar dynamics. This is explained by the authors' previously suggested model for the generation of a low-frequency branch of seismic emission as a result of amplitude instability of the seismic envelopes of acoustic oscillations in a structurally inhomogeneous medium. |
