Binaural Beats

An emerging form of sound wave technology

Binaural means “both ears,” and binaural beats are created by presenting slightly different frequencies to each ear. What results is a pulse in the brain that is the difference between the two frequencies... the perception of a third tone.  This third tone is called a binaural beat.

Binaural beats are said to provide many of the same benefits as meditation: lower stress, increase focus, aid with sleep and relaxation, boost mood, assist with pain management, and foster creativity.

To listen to binaural beats, a person will need a pair of stereo headphones and an MP3 player or another music system.

The Science

Sound Waves Creating Brainwave Shifts

What are binaural beats?

Binaural beats are an auditory illusion that occur when you detune a tone and send the two tones of slightly different frequency to each ear separately.

This difference in frequencies creates the illusion of the third sound—a beating rhythm. The brain has been shown to resonate at the same frequency as the binaural beats rhythm. For example, a tone that is de-tuned by 6 Hz for example, will create a resonance in your brain of 6 Hz. We measure 6 Hz to correlate with meditative, calm emotional/cognitive states. Currently, research shows that these states are able to be consistently produced in clinical settings.

Brainwave Glossary

Brain Frequencies and Cognitive States




Deeply relaxed, inward focused


Very relaxed, passive attention


Anxiety dominant, active, external attention, relaxed focus



Mixed Frequencies


Deep relaxation into sleep (gentle rest into deep sleep)


Relaxed passive attention with inward focus (early stages of creativity)


Relaxed focus with somewhat inward attention (good flow for studying)

Research has shown that in addition to effecting our states of consciousness, binaural beats have the important effect of synchronizing our brain hemispheres. Existing modalities such as EMDR and Neurologic Music Therapy have demonstrated the therapeutic benefits of brain synchronization.

Elizabeth's doctoral dissertation reviews the transformative effects of sound, specifically "The Effects of Auditory Binaural Beats on Consciousness and the Human Nervous System."

She designed a double blind, controlled study and tested her binaural beats formulas in Psytek Labs on the campus of the California Institute for Human Science. Watch a video of the Binaural Beats Pilot Study experiment here.

Her positive test results, published in the peer-reviewed journal “Frontiers in Human Neuroscience,” allow her formulas to be considered qualified as evidence-based formulas.

Listen to Elizabeth's iAwake interview: "Do Binaural Beats Really Entrain the Brain?"

Elizabeth, a professional musician, is writing, producing and working with other artists around the world in creating binaural beats music for all. She custom designs binaural beats formulas in the categories of sleep, relax, focus and move for her music.

Please be advised that binaural beats music is solely intended as a self-help tool for stress management and overall health and well-being and is not a substitute for licensed health care services. In the unlikely event that you experience any physical and/or mental discomfort while listening to binaural beats music provided by Sound Medicine, LLC, immediately discontinue use. Further, if you have a seizure disorder or heart condition, always check with your doctor before using any binaural beats music provided by Sound Medicine, LLC. Lastly, do not drive with your headphones and binaural beats music playing! Please refer to the Disclaimer for further information.
