The investigations of superconducting tunnel junctions as phonon gener-ators and detectors are reported. Theoretical predictions and the published results of the experimental research on such devices are briefly reviewed. The experimental results of the investigations of the current-voltage characteris-tics of fabricated tin tunnel junctions are presented and discussed, and then the measured current-signal transmission characteristics of pairs of identical tunnel junctions deposited on the corundum sample are analyzed and inter-preted. The results obtained are compared with the results o similar investi-gations reported in the literature.
