Brain Wave Frequencies
Delta - Deep Sleep: 0.5Hz - 4Hz
Theta - First Stage of Sleep: 4Hz - 8Hz
Alpha - Relaxation: 8Hz - 14 Hz
Beta - Alert and Focussed: 14Hz 30HZ

Mankind has been using techniques for altering brain wave frequency for generations. The drug states of the shaman, the chanting of the Buddhists, the dancing of the dervishes and the drumming of the Natives all serve to induce deliberate brain change.

The overall states are categorised into 4 broad groups, but this isn't really the whole picture. In the late 1980's, the "alpha" state appeared to garner much attention amongst the 'new age' community as being the state conducive to visualisation, healing, clairvoyancy and meditation. However, an alpha state achieved whilst idly relaxing on the settee will produce entirely different effects to an alpha state achieved in a bright, colourful Buddhist temple with the monks. Delta, Theta, Alpha and Beta refer to an overall state and does not give us an insight into specific neural activations occurring within the brain.

This is where the AudioStrobe CDs come into their fore. They supply both the induction of the altered state and the content/direction.

Also, other settings on the Proteus enable you to set the Proteus to induce the frequency of your choice (either a pre-programmed progressive session, i.e. Session 11 for deep meditation) whilst listening to a audio program of your choice. Nick Kemp's NLP/Hypnosis CDs, Richard Bandler's "Personal Enhancement" series and the Monro Institute Holosync series are all perfect for this use.

The Earth's electro-magnetic frequency is 8 cycles per second (Hz) and is known as the Schumann resonance. In its natural state the human body also resonates at a frequency of approx 7.8 -8 cycles per second. There is suggestion that using the Proteus set at this frequency will assist the brain to calm to its comfortable state. Certainly feedback from meditators suggests that using this frequency facilitates meditation greatly.

I have also seen it suggested that those who work in environment of high electromagnetic emissions, such as high rise offices full of computers etc. will benefit from brief daily sessions at the Schumann frequency.
