Binaural Beats, What are They?
You can create binaural beats by introducing two tones of different frequency into each ear. By playing one tone of 100Hz in one ear and playing another tone of 114Hz in the other ear, your brain will perceive a third tone or beat which is the phase difference between the two wavelengths of the original tones. This is how we naturally detect directional information using our ears.
As these two tones integrate in our brains, we call it a binaural beat. The resultant beat that we perceive would be 14Hz using this example. If the beat were lower, like say 4Hz, it would sound more like a wave. If the beat were higher like 20Hz, it would sound like a beat.
Binaural beats audio files can only be used with stereo headphones. Speakers cannot be used since the tones would mix in the air and produce more of a monaural beat. Those types of beats are usable in brainwave entrainment (bwe), however if the audio files in meant for binaural beats, that's how it should be used.
When first listening to binaural beats, your brain will need to adjust and you may hear a warbling like sound. If the tones are too loud it can easily cause headaches. In fact, you can set the tone so low, that you cannot knowingly hear them, however, the brain does have the ability to perceive infrasonic sounds.
Using binaural beats as a means for bwe is debatable. Binaurals can be used to produce beats from 0.235Hz up to 26.25Hz, after which the wavelength are too long. Dr. Gerald Oster did a lot of research when it comes to binaural beats. He concluded that they would be insufficient for bwe since the depth of each beat is slightly above a whisper.
The Monroe Institute (Hemi-Sync products), I-Doser, and Centerpointe (Holosync products) all use binaural beats for their personal growth and development products. The beats are often mixed with noise, music, ambiance or guided instructions. The advantage the binaural beat has over most other methods is its ability to entrain the brain to frequencies less than 4Hz.
There are other methods which are more efficient like isochronic tones, monoraul beats, low-pass filter modulation, cross-feed modulation, pitch modulation and auto pan modulation. Each type of technology has its own limitations and methods. We use a combination of these methods to produce the best results.
