Because they can be addressed separately and fed separate messages?

"The trademarked term Hemi-Sync signifies a patented combination of multiplexed

states of consciousness. "

attempt to corner the residential course market by blending standard subliminal 
tech with progressive relaxation hypnotic induction.
