Abstract
A device for inducing the brain waves of a user to assume a predetermined frequency including a playback device, stereo earphones, and at least one light mounted on glasses in front of each eye of the user. Three separate control signals are pre-recorded superimposed onto a single control track. This composite signal is read by the playback device and is decomposed into the separate control signals by filters in a decoder/controller. One control signal drives a first LED and another drives a second LED. The number of sinusoids within the first and second control signal determining the light intensity. The third control signal is passed alternately to two speakers, with the switching between the speakers being controlled by the state of the first and second control signal. Conventional earphones and a conventional tape player may be used. The invention also includes the method according to which the control signals are pre-recorded, played back, filtered, and applied to the lights and speakers.
