If you were to introduce two tones of different frequency into each ear, you could create binaural beats. For example, playing a tone with a frequency of 100Hz in one ear and playing a tone with a frequency of 114Hz in the other ear, will force the brain to determine the phase difference between the two wavelengths of each tone. We naturally do this to determine directional information.
A binaural beat is created when the signals integrate. Your brain will perceive a beat of 14Hz. Depending on the frequency of the phase difference it can sound like a wave or beat. If the frequency is low, it will sound more like a wave. If the frequency is higher is can sound like a very fast beat.
In order to make use of binaural beats, you must use stereo headphones. If speakers are used, the tones will mix in the air and produce a monaural beat. Monaural beats do have a place in the brain entrainment (bwe) world; however, if the track is meant for binaural, headphones must 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 for bwe has been the topic of some debates. Binaural beats can be used to product beats from 0.235Hz to 26.25Hz. Above this frequency, the wavelength are longer than the distance of the skull. However, Dr. Gerald Oster concluded that these beats would be insufficient for bwe because the depth of the beat is only about 1/10 the volume of 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 alternative audio methods that are more efficient that binaural beats, such as monaural beats, isochronic tones, cross-feed modulation, low-pass filter modulation, pitch modulation and auto-pan modulation. Each method has its own place and limitations. We use a combination of methods to get the best out of each session.
