Often people confuse isochronic tones and binaural beats – the terms themselves essentially point towards the same concept. This is understandable, but there is a fundamental difference. These two distinctive types of brainwave entrainment methods require a closer look.
Binaural beats affect the brain stem, causing it to produce auditory responses. These responses come from the superior olivary nucleus in each brain hemisphere. They occur as two different and separate auditory impulses interact.
The impulses originate in both of your ears and affect the brain. These impulses can differ in frequency between one Hz and upwards. To illustrate, if a binaural beat of 400 Hz is played to your right ear, and a differing tone of 410 Hz is played to your left ear, the difference between both tones is 10 Hz. This causes an “amplitude modulated standing wave”, which occurs when the two separate waves rotate in and out of sync.
These binaural beats aren’t “heard” in the common sense, but detected as an auditory sound instead. To summarize, they are heard when tones of different frequencies are presented to both ears. This causes the brain to become entrained to the frequency difference (of one frequency subtracted from the other). As the brain is entrained to that frequency, it begins to resonate to that frequency.
Isochronic tones, on the other hand, also work in a similar fashion . The isochronic tones coax the brain into specific rhythms as binaural beats do. That said, isochronic tones are much more modern and use the latest technology.
Isochronic tones are a stronger form of brainwave entrainment, utilizing equal intensity tones and boosting the pulse speed for a different effect. Your brain is synchronized with the rhythm as the more distinct, clean wave forms harmonize the brain. They also do it more efficiently and smoothly.
As a result, isochronic tones can more precisely target the desired brain wave frequency. They can have a major impact on your life as a result, allowing you to sleep more easily (without pills) and reduce anxiety to non-significant levels. The lower the brainwave frequencies, the more restful and relaxed you become. Isochronic tones are very useful for sleeping and resting.
There are even different levels of meditation that you can achieve using isochronic tones. For example, Theta Meditation requires you to play isochronic tones in the four to seven Hz range (and provide trance-like mediation), whereas Alpha Meditation requires eight Hz. This allows for higher levels of concentration while the user is awake.
As you listen to frequencies (10 Hz as an example), the brain starts to produce brainwaves of that same frequency. Binaural beats and isochronic tones (the two main brainwave entrainment recording types) take advantages of this to provide levels of relaxation or focus, depending on what the user is trying to accomplish.
That said, isochronic tones are a significant upgrade to binaural beats. They utilize better technology and produce superior results. Binaural beats are a slightly older form of accomplishing similar goals, but require headphones to work. Isochronic tones encourage your brain to synchronize with the rhythms, something binaural beats cannot do.
