Electromagnetic frequencies (EMF) refer to the waves of energy that are created by the movement of charged particles. These waves can be found in natural environments, for example, from the sun and lightning.  These naturally occurring environments produce EMF in the low Hz ranges. Man-made EMF from electronic devices such as cell phones, Wi-Fi modems, and cell towers emit EMF in the high MHz and GHz ranges. 

Binaural Beats, on the other hand, are an auditory perception created by the brain when it hears or perceives two different Hz frequencies. The Binaural Beat effect has a beneficial impact on brainwaves and is used to promote relaxation, and meditation, and to address sleep disorders, depression, anxiety, and other ailments. Depending on the frequencies used, users may experience reduced depression, reduced anxiety, and improved sleep.

Simply plug it in, turn it on, place it within 18 inches of your pillow, and keep it on 24/7. Most users notice improvement in sleep quality in 5 to 14 days.
