Some results of investigations of the behavior of seismo-acoustic resonators under the action of different processes occurring at the interface of the ocean, atmosphere, and land are given. Certain stable groups of frequencies are revealed in the oscillation spectra of envelopes of the signals received from these resonators. Possible relation between the behavior of these envelopes and the dynamics of recorded shearing strains is discussed. Some other results of signal recording in the neighboring media are also presented.
