Binaural rhythms are an artifact of the brain, imaginary sounds of controlled music, which the brain perceives (“hears”), although there are no real sounds.

To observe binaural rhythms, it is enough to put on the stereo, in which signals are given to different ears, slightly different in frequency, the brain difference perceives as natural bends of the low frequency. In order for such beats to be heard, their tones frequency should be not higher than 1000-1500 Hz, and the frequency difference is not higher than 30 Hz, but still mainly no more than 25 Hz. With a greater difference in frequencies, a person hears two separate tones, and the beating does not arise. From a physical point of view, this is the fusion of two waves, the phases of which periodically coincide, thereby creating a side wave of a low frequency.

Binaural rhythms are the subject of a study of neurophysiologists, in particular, studying hearing. In addition, binaural beats affect the brain, causing waves in it, which can be registered using electroencephalography.

Binaural hearing

The term “binaural”, “binaural hearing” refers to the ability of man and animals to determine the direction of the sound source, thanks to the differences in the parameters of sound waves that come to different ears.

In a musical record, if you give signals of different amplitudes (volume) on the left and right headphones, this can be created by the illusion, as if a musical instrument is on the left or right. For sound sounds, the phase (delay) also has.

The shells of the ears and the bones of the skull unequally miss the sounds of different frequencies, therefore, by changing the spectrum of sound, you can create the illusion that the sound source is behind or in front.

Binaural hearing is not directly related to brain waves. But music can affect a person’s mood and, accordingly, an encephalogram will change.

Unlike “binaural hearing”, the term “binaural rhythm” is very often found on esoteric sites, and binary rhythms are attributed to various mystical properties.

The term itself is not entirely correct, since the described effect occurs regardless of whether the sounds of different frequencies are presented to different ears or one. This effect is known to musicians as a beating. Thanks to him, it is convenient to configure the tools, since the beating allows you to notice that two strings are a little not in unison.

In a similar way, the amplitude vibrato is perceived - the effect also used in music.

Since these effects to musicians have long been known and mastered, the mystical properties are not attributed to them.

A similar effect is a common interval between two sounds, only very small, like a commander, limma. Different intervals also affect the mood in their own way, etc. For example, a small second, literally, “cuts” and “chop” hearing.
