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).
E.g. a Focus 26 beat has 5 carrier frequencies (400-900 Hz) which are played simultaneously at different db levels (n.a.) and a theta/delta BB frequency ranging from 4.2-3.9 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.
