Abstract. Are carried results of the detection and study of fundamentally new physical phenomenon - generating undamped temperature waves, which can exist in different environments only at certain frequencies, the value of which depends on the time of the local relaxation of thermal excitations in these environments (the thermalization time). In the air, under normal conditions, the minimal frequency of a such wave corresponds to 70-90 MHz, and in metals and semiconductors, it is 1012-1014 Hz. In the experiments, these waves are generated via cavitation processes and registered in the air at a distance of 2 m, and this distance is limited only by experimental conditions.

Keywords: cavitation, shock waves, acoustic detector, thermal wave, the heat equation, thermal relaxation
