METHOD FOR APPLYING ULTRASONIC TREATMENT TO HUMAN ORGANISM Russian patent published in 2004 - IPC

FIELD: medicine.

SUBSTANCE: method involves recording audibility threshold frequency dependence by sending control signal to acoustic system entry. Signal level is varied from a minimum to one causing acoustic sensations in patient. The value is recorded and frequency-dependent coefficient is calculated from formula K_l=20lg threshold Um_l / U₀, where l is the harmonic number, threshold Um_l is the l-harmonic audibility threshold voltage amplitude, U₀ is the input voltage minimum value. The biosignal is recorded. Acoustic action is formed by varying sound parameters in criterion relationship depending on biosignal. When forming the acoustic action, the input signal is additionally multiplied by frequency-dependent coefficient K_l value.

EFFECT: enhanced effectiveness of psychophysiological treatment.
