What Are Monaural Beats?
Monaural beats have a pulsing sound that is somewhat smoother than binaural beats. It is not necessary to use headphones when listening to them, although headphones seem to give better results and also help to eliminate outside distractions. With monaural beats, the same sine wave is introduced to each ear, so that brain does not have to do the work of creating a tone. Monaural beats have been fairly well researched and found to be effective for brain retraining.
