It is claimed that binaural beats with this pattern can induce deep sleep, help to heal the body and may even lower cortisol levels, reducing stress and providing anti-ageing benefits. It is generally associated with deep, dreamless sleep and the unconscious mind.

Delta: The delta states frequency range is 0.5-4 Hz.

But, before you do, itвЂ™s worth understanding the different types of binaural beats and what benefits they may be able to provide you with. Luckily, there donвЂ™t seem to be any dangerous side effects to using binaural beats and all it takes to find some is a single YouTube search, meaning the best way to know for sure whether binaural beats are for you is simply to try them out for yourself. However, as the authors point out, it remains to be seen whether this entrainment actually leads to improved cognitive performance or changes to mood and sleep patterns. The most comprehensive studyВ done on the subject so far proves that they do alter brain frequencies as advertised.

The main point that is still up for debate is not even whether binaural beats do in fact lead to brain entrainment. This is well understood and widely accepted by the scientific community. For example, if a sound with a frequency of 200 Hz is played in one ear and another of 210 Hz is played in the other, the brain will focus in on the 10 Hz difference between them and hear only a single low-frequency beat. When done correctly, the brain naturally perceives the difference between the two sounds rather than their sum or individual characters. One sound is played into the right ear and the other the left, meaning headphones are required for this trick to work. Even if this does turn out to be largely a placebo effect, it might be one that works for you.ДЄs mentioned above, a binaural beat is the combination of two distinct yet similar sounds played simultaneously to create an auditory illusion that tricks the brain into only hearing a single, lower frequency beat. However, there is plenty of strong anecdotal evidence that they do help people. For now, despite the fact that a number of studies have been done on the subject, there is no hard scientific proof of the efficacy (or lack thereof) of binaural beats.

The science is complicated yet the idea is really quite simple and possibly even brilliant, although the jury is still out on that last part. Proponents of binaural beats claim that this effect can be used to create neural firing patterns that correspond with various states of consciousness that are beneficial for everything from sleep to studying (more on this later). Also known as brainwave synchronization or neural entrainment, this effect occurs when the brain synchronizes brainwave frequencies with an external stimulus. These two slightly different frequencies are played in tandem to create an effect in the brain called brainwave entrainment. As the name suggests, a binaural beat is the combination of two distinct sounds that creates one indistinguishable beat. Before understanding how binaural beats work, or if they work at all, we need to unpack what they actually are.
