Subliminal learning enjoys wide use today and subliminal tapes are being manufactured by a number of companies in the United States alone. Several decades of scientific study indicate that subliminal messages can influence a humans attitudes and behavior. Subliminal, in these discussions, can be defined as below the threshold of audibility to the conscious mind. To be effective however, the subliminally transmitted information (called affirmations by those in the profession) must be presented to the listeners ear in such a fashion that they can be perceived and decoded by the listeners subconscious mind. We are referring to audio information in this discussion, however, information could be inputted into the subjects subconscious mind through any of the bodys sensors, such as touch, smell, sight or hearing. As an example, early development work in the subliminal field utilized motion pictures and slide projections as the medium. Early research into visual and auditory subliminal stimulation effects is exemplified by U.S. Pat. Nos. 3,060,795 of Corrigan, et al. and 3,278,676 of Becker. U.S. Pat. No. 4,395,600 of Lundy and Tyler is representative of later developments in todays subliminal message techniques. The majority of the audio subliminal tapes available today are prepared using one basic technique. That is, the verbal affirmations are mixed with, and recorded at a lower level than, a foreground of music or sounds of ocean surf or a bubbling mountain brook or other similar masking sounds. The affirmations are generally recorded 5 decibels (db) or so below the foreground programming and regenerative automatic gain control is usually applied to permit the affirmations to change their recorded amplitude in direct proportion to the short term averaged amplitude of the continually varying foreground material. In other words, the volume of the affirmations will follow or track the volume changes of the foreground programming, but at a lower volume level. Circuit provisions are also usually included to gate the affirmations off when the music amplitude is low or zero. This insures that the affirmations cannot be heard during quiet program periods. Thus, todays subliminal affirmations can be characterized as being masked by music or other sounds, of constantly changing amplitude and of being reduced or cut off entirely during periods of low or quiet foreground programming.
