All of the predecessor rhythmic sound products induced states of either alpha or theta consciousness. These are specific states that are characterized by well-defined electrical activity within the brain (as measured by an EEG) and are associate with corresponding physiological changes. Both of these states are distinct from normal waking, active consciousness, which is called beta.
However, most individuals can readily shift to these altered states within a few minutes using basic techniques. Approximately 90% of the adult population can enter alpha by closing their eyes and taking a deep breath. By engaging in basic meditation techniques such as rhythmic deep breathing, repetition of a sound/phrase or internally focusing the eyes at a distinct point one will readily enter the theta state. Therefore the existing products do not produce significant audio-neurological coupling.
There is a fourth state of consciousness which is called delta. It is normally encountered only in the deepest level of sleep, a level that is so deep that the total amount of time spent in delta during a typical night's sleep is less than one hour - it may even be less than 20 minutes!
The criteria for exploring significant audio-neurological coupling had been
determined; the repeatable induction of the delta state in an awake and
alert individual!
After numerous trials a set of rhythmic conditions was found that induced waking,
delta consciousness.
The EEG data below (click any image for a larger picture) was taken just prior to and
while listening to the rhythmic components of RAS-1.
The various colors on the graphs correspond to the beta (red), alpha (yellow), theta (green) and delta (blue) states mentioned above. The spectrum on the left was obtained while resting, with the eyes closed, just prior to exposure to the audio stimulation. You'll note the presence of a pronounced alpha (yellow) peak at 9 Hz. The same individual then listened to the rhythmic patterns used in RAS-1 for 20 minutes (EEG spectrum on the right). Here you'll note the presence of a pronounced delta (blue) peak at 2.5 Hz. It is important to realize that while in the delta state this person, though deeply relaxed and with his eyes closed, was fully conscious.

Please note that I have NO training in the medical profession, that I make NO claims of medical competence and that I am TOTALLY incapable of rendering any medical opinion. I am trained as a scientific researcher, having worked predominantly with the growth, processing and characterization of thin films. My area of greatest expertise was in ultra-high vacuum surface spectroscopy. I approach the analysis of rhythmic audio stimulation in an analogous manner to my spectroscopic investigations.
