It is human tendency to suspect. What if one tells you; all your mental disorders can be solved with one single tool? What if you can practice meditation as deep as Zen monk without years of isolation and practice? Many new brainwave entrainment programs make such exaggerated claims. It pops a question in our mind; are highly successful and reputed programs like HemiSync and Quantum Mind Power scam too?

There are definitely many bogus programs are there. But the science behind brainwave entrainment is based on fundamental feature of our brain called Frequency Following Response (FFR). Basically brainwave entrainment is brain’s electrical response to shift its frequency similar to frequency of external stimulus.

Naturally, we can experience it while listening to chirps of birds or sound of ocean waves; it soothes our minds while noise of traffic irritates us. Why? Brain follows the dominant frequency of the environment and aligns with it by entraining its own frequency. Brainwave Entrainment programs uses precisely created sounds carrying particular frequency with binaural/monaural/isochronal tones for stimulating brainwave entrainment. These sound programs can be used for many practical uses and it has proved very successful in delivering what it promises.

Lower frequencies of brain are conducive for many developmental and therapeutic purposes. Frequency is speed at which signal travels and it is measured in cycles per second or Hz. Frequencies are classified in 4 categories.
Beta frequency 14 – 35 Hz
Alpha frequency 7 – 14 Hz
Theta 3.5 – 7 Hz
Delta lower than 3.5 Hz

Here is a list of which frequency range to be targeted for a given purpose.
Reducing Stress: Any frequency below 11 Hz will be useful
Relaxation: 5 Hz to 10 Hz
Meditation: 4 Hz to 7 Hz. Choose light Theta for meditation for beginners.
Hypnosis: 8 – 10 Hz, from light alpha to deep alpha.
Deep Sleep: Begin with deep theta range around 4 – 6 Hz, then keep on reducing and settle at deep delta around 1.5 – 2.5 Hz
Visualization: 6 – 10 Hz
Subliminal Programming: from 5 – 7 Hz for different purposes like gaining confidence, cultivating self discipline for implementing exercise and diet tips to lose weight successfully, overcoming smoking and gaining self confidence.
Accelerated learning: 7 – 9 Hz while studying or reading. It improves concentration, memory and retention power.
Psychic Abilities: 5 – 7 Hz is very effective for developing intuition, remote view and higher states of awareness.
