Binaural beats were discovered in 1839 by a German scientist named Heinrich Dove. Ever since, they have been touted as one of the most popular forms of brainwave entrainment, along with monaural beats and isochronic tones.
Listening to binaural beats can quickly create states of quiet meditation, which is excellent practice for lucid dream induction. What's more, they don't require any stringent mental focus - only your willingess to lie quietly and relax.
"Slow modulations called binaural beats are perceived when tones of different frequency are presented separately to each ear. The sensation may show how certain sounds are processed in the brain.
If two tuning forks of slightly different pitch are struck simultaneously, the resulting sound waxes and wanes periodically. The modulations are referred to as beats; their frequency is equal to the difference between the frequencies of the two original tones.
Binaural beats have been widely regarded as a mere curiosity. A recent textbook on hearing does not mention them at all. Yet the measurement of binaural beats can explain the processes by which sounds are located -- a crucial aspect of perception. It is possible that hormonally induced physiological behavior changes may be made apparent by measuring the binaural-beat spectrum."
~ Gerald Oster, Scientific American, October 1973
The human brain treads many different frequencies every day, each depicting your current level of consciousness.
For instance, the THETA brainwave frequency occurs during states of still alertness, light sleep and dreaming. It is marked by 3-6 cycles (Hz) per second.
It is possible to entrain this frequency through sound. But we can't simply play a 6 Hz frequency in the ear and expect the brain to respond, because we can't even detect sounds that low. The solution with binaural beats is to play two separate frequencies into each ear (eg, 130Hz in the left / 136Hz in the right).
The brain compensates for the difference in frequencies heard in the right and left ear, creating an internal frequency of 6 Hz, and thereby entraining a THETA operating state. It then produces a frequency following response. Because the effect is produced within the brain it is critical to wear headphones.
Studies have produced a general consensus on what types of effects you may feel while listening to binaural beats. I have experienced various phenomena usually associated with relaxation and mediation:
These effects are the result of listening to binaural beats as well as a conscious effort to meditate. With practice this helps prepare my mind for more lucid dreams.
BrainSync's Lucid Dreaming MP3 features a combination of soft ocean waves, binaural beats and subliminal messages to help you meditate, reflexively question the dreamstate, and ultimately become lucid.
Going deeper into a trance-like state of meditation, you'll enter the Theta state where brainwave activity slows almost to the point of sleep, but not quite. Theta is one of the more elusive and extraordinary realms to consciously explore. It is also known as the twilight state which you normally only experience fleetingly upon waking, or drifting off to sleep.
In Theta, receptivity is heightened and you are able to access knowledge and information that normally lies beyond your conscious awareness. As flashes of vivid imagery dance before your mind's eye, you may feel a "floating" sensation as your mind expands beyond the boundaries of your body. In this deeply relaxed state don't be surprised to receive sudden insights, inspiration or a sense of knowing... as well as vividly emerging dream scenes. Visit BrainSync.
