200 Hz pure delta binaural brainwaves for deepest meditation and dreamless sleep
To experience the binaural brainwaves perception, it is best to listen with headphones on moderate to weak volume – the sound should be easily heard, but not loud. Note that the sound appears to pulsate only when heard through both earphones.
Brainwave speed is measured in Hertz (cycles per second) and they are divided into bands deliniating slow, moderate, and fast waves.
DELTA WAVES (1 TO 4 HZ)
Delta brainwaves are the slowest but loudest brainwaves (low frequency and deeply penetrating, like a drum beat). They are generated in deepest meditation and dreamless sleep. Delta waves suspend external awareness and are the source of empathy. Healing and regeneration are stimulated in this state, and that is why deep restorative sleep is so essential to the healing process.
THETA WAVES (4 TO 9 HZ)
Theta brainwaves occur most often in sleep but are also dominant in the deep meditation. It acts as our gateway to learning and memory. In theta, our senses are withdrawn from the external world and focused on signals originating from within. It is that twilight state which we normally only experience fleetingly as we wake or drift off to sleep. In theta we are in a dream; vivid imagery, intuition and information beyond our normal conscious awareness. It’s where we hold our ‘stuff’, our fears, troubled history, and nightmares.
ALPHA WAVES (9 TO 13 HZ)
Alpha brainwaves are dominant during quietly flowing thoughts, and in some meditative states. Alpha is ‘the power of now’, being here, in the present. Alpha is the resting state for the brain. Alpha waves aid overall mental coordination, calmness, alertness, mind/body integration and learning.
BETA WAVES (13 TO 39 HZ)
Beta brainwaves dominate our normal waking state of consciousness when attention is directed towards cognitive tasks and the outside world. Beta is a ‘fast’ activity, present when we are alert, attentive, engaged in problem solving, judgment, decision making, and engaged in focused mental activity. Beta brainwaves are further divided into three bands; Low Beta (Beta1, 13-16Hz) can be thought of as a ‘fast idle, or musing. Beta (aka. Beta2, 16-23Hz) as high engagement. Hi-Beta (Beta3, 23-39Hz) is highly complex thought, integrating new experiences, high anxiety, or excitement. Continual high frequency processing is not a very efficient way to run the brain, as it takes a tremendous amount of energy.
GAMMA WAVES (39 TO 43 HZ)
Gamma brainwaves are the fastest of brain waves (high frequency, like a flute), and relate to simultaneous processing of information from different brain areas. It passes information rapidly, and as the most subtle of the brainwave frequencies, the mind has to be quiet to access it. Gamma was traditionally dismissed as ‘spare brain noise’ until researchers discovered it was highly active when in states of universal love, altruism, and the ‘higher virtues’. Gamma rhythms modulate perception and consciousness, disappearing under anaesthesia. Gamma is also above the frequency of neuronal firing, so how it is generated remains a mystery. The presence of Gamma relates to expanded consciousness and spiritual emergence.
