Binaural Beats are a pretty effective way to induce meditative among other types of brainwave states. How do I know ? I use 'em. Ahhhh.....What are Binaural Beats you ask......?
Binaural beats or binaural tones are low-frequency pulsations in the perceived loudness of a sound when two tones at slightly different frequencies are played separately, one into each of the subject's ears, using binaural headphones. The frequency of the tones must be below about 1,000 to 1,500 hertz. The difference between the two frequencies must be small (approximately below 30 Hz) for the effect to occur; otherwise the two tones will be distinguishable and no beat will be perceived. The effect was discovered in 1839 by Heinrich Wilhelm Dove.
Interest in binaural beats can be classified into two categories. First, they are of interest to neurophysiologists investigating the sense of hearing. Second, there are those who believe that binaural beats may influence the brain in more subtle ways through the entrainment of brainwaves and can be used to produce relaxation and other health benefits.
"Directly" using an auditory stimulus is impossible, since the ears cannot hear sounds low enough to be useful for brain stimulation. Therefore binaural beat frequencies must be used.
According to this view, when the perceived beat frequency corresponds to the delta, theta, alpha or beta range of brainwave frequencies, this causes the brainwaves to entrain to or move towards the beat frequency. For example, if a 315 Hz sine wave is played into the right ear and a 325 Hz one into the left ear, the brain is supposed to be entrained towards the beat frequency (10 Hz, in the alpha range). Since alpha range is usually associated with relaxation, it is supposed to have a relaxing effect.
Frequency range.........Name..........Usually associated with:
>40 Hz................Gamma waves
13-40 Hz.............Beta waves.........Attention
7-13 Hz...............Alpha waves.......Relaxation (awake)
4-7 Hz.................Theta waves.......Dreams, deep meditation
<4 Hz..................Delta waves.......Deep dreamless sleep
There are programs out there you can try it out yourself. Just a pair of headphones and a computer. You can bring yourself into a meditative state within 60 seconds and set the duration and it will bring you out of it back to a "waking" state....all simply through sound.
This isn't Voodoo...it's science that dabbles in the metaphysical...try it...
