PURPOSE: To bring human consciousness to a desired state by modulating beat signals of both bars, taking account of electroencephalograms representing a specific consiousness state. CONSTITUTION: This is a method to induce a variety of states of human consciousness, consisting of a process to form a brain wave form reproduced to show a desired state of consciousness; a process to superpose a brain wave form onto two pairs of individual carrier waves, using a stereo sound; a process to generate different beat frequencies via two pairs of individual carrier waves as used in a process to superpose a brain wave form; and a process to give to the human left/right ears the beat frequency signals are gained so that a desired state of consciousness is induced. This allows a variety of states of human consciousness to be obtained, such as inducing a sleeping state, a conscious concentration, a mental atony and the like.
