Monaural Beats

Monural beats are very similar to binaural beats. In fact, back in the 1800's when binaural beats were first discovered, it was believed that monaural beats were a special type of binaural beat, although this is clearly not the case. Monaural beats, just like binaural beats, are created by the pitch/frequency difference in two seperate incoming tones. Monaural beats differ from binaural beats in that the tones are created in the ear, rather than in the brain, as with binaural beats.
Monaural beats are more effective in brainwave entrainment versus binaural beats. That is, they evoke a stronger cortical response in the brain. This is due to the fact that the combined tone's beats/pulses are farther apart, making them easier for the brain to detect. Another benefit of monaural beats is that they do not require the use of headphones. You can see the difference between binaural and monaural beats in the following pictures:

Nirvanic Mind™ products occasionally utilize monaural beats, although not often, as we find other forms of entrainment more flexible and effective. We also have used them in a harmonic box x configuration first described by James Mann. It incorporates both binaural and monaural beats in a harmonic formation.
