Binaural beats

This is the Nexus Binaural beats (BB) site for a comprehensive overview over various BB resources.

Brain waves

Frequency range	Name	Usually associated with:
> 40 Hz	Gamma waves	Higher mental activity, including perception, problem solving, fear, and consciousness
13–39 Hz	Beta waves	Active, busy or anxious thinking and active concentration, arousal, cognition, and or paranoia
7–13 Hz	Alpha waves	Relaxation (while awake), pre-sleep and pre-wake drowsiness, REM sleep, Dreams
8–12 Hz	Mu waves	Mu rhythm, Sensorimotor rhythm
4–7 Hz	Theta waves	Deep meditation/relaxation, NREM sleep
< 4 Hz	Delta waves	Deep dreamless sleep, loss of body awareness

BBs and pink noise

"Masking binaural beats with pink sound does not decrease their effectiveness. Note: Pink sound is mixed with Hemi-Sync's binaural beats to provide a sensory integration link with out-of-body experiences. Research has shown that noise does not obscure the initial perception of binaural beats and it provides a ganzfeld environment conducive to altering states of consciousness."

Monroe's Focus freqs

• Focus 24 50[0.75], 400[3.9], 503[4.0], 600[4.0], 750[4.0], 900[4.0]
• Focus 25 503[4.0], 600[4.0], 750[4.0], 900[4.0]
• Focus 26 400[3.9], 503[4.2], 600[4.0], 750[4.0], 900[4.0]
• Focus 27 Same as Focus 26

Example: The notation 503[4.2] should be understood to represent a beat frequency of 4.2 Hz between two carriers equally separated from 503 Hz (i.e., 500.9 and 505.1 Hz).

Although the frequencies were measured, the relative amplitudes of the tones were not, so the results will not be completely identical to those from the Monroe Institute tapes.
