The isochronic tones beat at a rate of between of 12-15Hz, throughout the video. When referring to brainwave activity, the 12 to 15Hz range is known as SMR (Sensorimotor Rhythm). The tones work to stimulate your brainwaves and increase activity within this SMR range, which offers many potential benefits.
How can you use it and benefit from it?
12-15Hz is at the bottom of the Beta range. Increasing low Beta activity can increase focus, but as it's not too intense, it can be used as a general study aid to boost concentration.
SMR is a good mid frequency range which can be helpful in reducing anxiety and stress, where individuals may be experiencing an increase in very high frequency brain activity.
It can also be used to raise someone's mood and energy levels, providing support and relief for depression, where someone will be producing more slow wave activity.
It's an ideal frequency range for those people who experience both anxiety, stress and depression at similar times.
