What are Binaural Beats?

Binaural beatsHuman Ears Are Binaural – Basically, we hear with both our ears (unless we are hearing impaired in some way). Heinrich Wilhelm Dove discovered that when two different frequencies are played into each ear, the brain compromises by producing a third sound known as a binaural beat or tone. In effect, it’s a beat frequency. So if 400 Hz is played in one ear, and 410 Hz in the other, the binaural entrainment rate would be 10 Hz. To be effective in therapy, binaural beats need to ride on a ‘carrier’ sound, such as a relaxing or focused musical track, ambient sounds (especially nature), and headphones must be used.

The difference between the two frequencies could be called a “sub harmonic” – a sound that is below the threshold of human hearing. However, this sub-harmonic binaural frequency may still be detected as a slight pulsing sound. This pulsing, or beating, is why they are called binaural “beats”.

When a sound reaches your ears, your brain instantly works to determine where that sound came from. If your hear a noise that originated slightly to your left, then the sound will not only be a little louder in your left ear, it also arrives at your left ear a few milliseconds sooner than it arrives at your right ear. You may not notice this effect on a conscious level, but your brain certainly does.

How Do Binaural Beats Affect The Brain?

Your brain is very sensitive to small variations in the frequency of sounds, and to the way those sounds reach your ears. When you listen to binaural beats, your brain is subjected to an effect that it perceives as a constant fluctuation in the directionality of the sound. This is really just an auditory illusion.

Binaural BeatsBinaural beats cause the brain to adjust its dominant frequency to match the  sub-harmonic frequency of the beating sound. This is what is known as the “frequency following response” (FFR).

Why Are Binaural Beats Effective?

The reason why binaural beats are so effective is because we can take advantage of the FFR by creating binaural frequencies that help to induce specific brainwave frequencies. For example, we know that someone who is in a state of deep meditation may have a dominant brainwave frequency of around 6 Hertz (6 cycles per second). When you listen to binaural tones that have been programmed to produce a 6 Hertz sub harmonic frequency, your own brainwaves will follow the frequency of the beat, and will naturally adjust in sympathy.

In other words, binaural frequencies can be used to adjust the dominant frequency of your own brainwaves, leading to altered states of consciousness, from light relaxation, to deep sleep. Most commonly they are used to accelerate and deepen meditation.

By themselves, binaural beats are not particularly restful or pleasant to listen to. However, when blended beneath ambient music and nature carrier tracks, you are barely aware of them but your brain picks them up and thereby induces the desired state.

What Are The Advantages?

When your brain hears binaural beats or tones, it naturally goes into a state of relaxation or focus. When we add the right kind of carrier tracks, we set up an optimum platform for adding in special therapeutic and subliminal messages for effective and rapid change that your subconscious mind can easily absorb.

Binaural beats have been added to many of our MP3s and have been paired with the right kind of carrier music to create the desired effects of the audio title.
