Some features of sensing by human cochlear neurons of the infrasound vibrations generated by a change in frequency and volume of the audible range are discussed. It has been shown that auditory neurons respond to a volume envelope that selects corresponding infrasonic frequencies for their further processing. This mechanism is possible if the ear operates nonlinearly performing detection with further time averaging of no less than over 40–50 ms. If the frequency of the sound code coincides with any rhythm of the brain, resonance may occur, increasing the amplitude of the corresponding rhythm.
