Robert A. Monroe, founder of Hemi-Sync, is internationally known for his work with audio sound patterns that can have dramatic effects on states of consciousness. Monroe observed, during his early research, that certain sounds create a Frequency Following Response in the electrical activity of the brain.

Those observations led to some remarkable findings dealing with the very nature of human consciousness. Researchers learned specific sounds could be blended and sequenced to gently lead the brain to various states ranging from deep relaxation or sleep to expanded states of awareness and other “extraordinary” states. This compelling research became the foundation of a noninvasive and easy-to-use audio-guidance technology known as Hemi-Sync.

Hemi-Sync can help people of all ages improve the quality of their sleep and dreams. Hemi-Sync have over 100 different sleep and dream recordings to help you fall asleep and sleep deeply.
