METHOD FOR TRANSFORMING VERBAL AUDIO INFORMATION TO THE PERCEPTION LEVEL BELOW THRESHOLD UNDER PSYCHOPHYSIOLOGICAL ACTION APPLIED Russian patent published in 1999 - IPC

FIELD: medicine. SUBSTANCE: method involves matching background audio signal and transformed information signal carrying verbal information. The information signal is subjected in advance to spectral analysis and multistage transformation by carrying out amplitude-phase modulation, frequency spectrum compression and setting lower and upper bound to frequency bandwidth. restriction. Audio signal superposition is carried out under constant relation of information signal power to be below that of the background one. Summing up audio signal is sent to acoustic analyzer of the testee to record a number of bioelectric values making input to corrected information signal after program processing being applied. EFFECT: produced state of hypersuggestibility; enabled unconscious suggestion; optimum influence upon human psychophysiological state. 7 cl
