Quickly motivates the listener by ramping up to 18 Hz beta. This program energizes and motivates the listener by ramping from 15 Hz to 18 Hz beta, relieving symptoms of fatigue and listlessness Use this program in the morning or afternoon for an energy boost and increase in motivation. Your eyes can be open or closed for this program. This program contains Isochronic tones and therefore can be used with or without headphones. If you are in a noisy environment, it is recommended to use headphones. Isochronic pulses are modulated into the background sounds or a carrier wave tone to produce the frequencies that create the desired brain waves. Since they do not rely on stereo imaging to produce the brain waves, Isochronic programs can be played on any speaker system. The Isochronic tones produce a fluttering sound similar to a helicopter so if you hear a sound like this, it is normal.
