Audio Frequency Stimulation

Audio Frequency Stimulation

A binaural beat is the combination of two audio frequencies or tones. One tone is directed to the left ear while the other tone is directed to the right ear. Say the left ear is receiving a tone of 180 Hz and the right ear is receiving a tone of 190 Hz. What the brain actually “hears” is 10 Hz, which is the difference between the two and is known as the offset frequency. Dual binaural beats are created simply by combining two totally independent binaural beats. The resulting four channels of audio beats work together to generate several offset frequencies. The resulting frequency variations are very dynamic and complex, and have become the ideal method for maximizing brainwave entrainment. In fact, dual binaural beats are so effective that listeners can utilize stereo speakers rather than headphones and still receive the full effect. White noise is sometimes combined with either binaural beats or dual binaural beats. This method is limited, however, to session designs targeting relaxation and meditative states.

Phase settings for pulsed tone and white noise are connected to the light settings. By combining sound with light, you can utilize eight different phase settings: in phase, out phase, cross phase, sound out phase with lights in phase, sound in phase with lights out phase, clockwise motion, counterclockwise motion and front/back phase. All phase settings are rather self-explanatory and are described in more detail in the owners manual that comes with your light and sound instrument. Phase settings with dual binaural beats involves a little math and some experimenting. For information on creating sessions utilizing binaural and dual binaural beats, refer to the Suggested Reading section.
