[Frequency range of the auditory effect of UHF]

Zero beats of radiosound with an acoustic signal from an electrodynamic emitter in the frequency range up to 8 kHz were recorded in a natural experiment, which were not obtained earlier. It has been shown that the zero beats between the acoustic tonal signal and the first harmonics of the impulse succession of UHF are recorded in the points which correspond to low values on the threshold curve of UHF auditory effect.
