Binaural means to listen with two ears. In 1839, a physicist named Heinrich Wilhelm Dove discovered that a person hears the sound of continuous beats when waves of two different frequencies are introduced to his both ears simultaneously.
Since then binaural beats has kept gaining popularity. Especially, in the past few years a lot of people have become too interested in it due to the buzz created by some advertisers that it can help people to enhance their mind power.
Today, people are widely using binaural beats for meditation because of its utility in taking a person into deep relaxed states of mind and in causing the altered states of consciousness.
A plethora of self help products is available now that uses brainwave entertainment technology, which are the audio waves used to stimulate brain using binaural beats, they claim that a person can achieve various mind states which even includes the deeper levels of meditation reached by Zen monks.
Binaural beats are not real, it is an auditory illusion, so what you hear as beats is simply happening because of your brain’s response to these tones.
The third illusory tone that you will hear is a low frequency one which in most cases is pretty much close to the difference between the frequencies of the actual two tones.
The maximum frequencies of the two tones must not be greater than 1000 Hz for the beating to be evident. The difference between the frequencies of two tones must be less than or equal to 30 Hz for best results.
If the above conditions are not met the two tones will be heard discretely without the person being able to sense the third low frequency tone.
Binaural beats requires the use of a good quality of headphone or earphone, since two different frequency audio will be played on your both ears this is not possible with the use of the regular speakers.
Before I get to the points, I want you to understand that binaural beats have indeed proved to be very effective in changing one brain’s state to a great extent still the benefits that I am going to write below are not research based, these are just some common advantages lot of people have had with the use of brainwave entrainment. But, there are chances that you may not experience any significant change.
Even though I have seen the effects of binaural beats in the past and I have known many people who regularly use these audios for various purposes, I still am not in favor of the use of these tones due to some not so good experiences I have had with it, I have talked about in more detail in this post – The Harmful Effects and Dangers of Using Binaural Beats.
If you are very much interested to use some sound related aid for deep meditation then I would suggest you to try Omharmonics technology, it is based on brainwave entrainment, but they have worked over the annoying part of binaural beats using some MRT technology and I have found it pretty effective.
