Binaural beats. How do they work?

Hello people! Today we'll be talking about binaural beats.

Binaural beats, or binaural tones, are sounds that affect the brain and can induce numerous effects. This effect was discovered in 1839 by Heinrich Wilhelm Dove and earned greater public awareness in the late 20th century based on claims coming from the alternative medicine community that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.

The brain produces a phenomenon resulting in low-frequency pulsations in the amplitude and sound localization of a perceived sound when two tones at slightly different frequencies are presented separately, one to each of a subject's ears, using stereo headphones. A beating tone will be perceived, as if the two tones mixed naturally, out of the brain. The frequencies of the tones must be below 1,000 hertz for the beating to be noticeable.

Binaural beats are of interest to neurophysiologists investigating the sense of hearing.

Binaural beats reportedly influence the brain in more subtle ways through the entrainment of brainwaves and provide other health benefits.

For example, this beat helps with concentration. I do not own this video.


There are many more beats all over the internet. Ones that deal with relaxation, improved learning and more. Check 'em out.
