Binaural beats are a type of auditory illusion created by the brain when it processes two slightly different sound frequencies played simultaneously in each ear. When the brain hears these two frequencies, it creates a perception of a third frequency that is the difference between the two. This third frequency is known as the binaural beat.
For example, if a tone of 200 Hz is played in one ear and a tone of 210 Hz is played in the other ear, the brain will perceive a binaural beat of 10 Hz. This beat can be manipulated by adjusting the frequency of the tones played in each ear.
Binaural beats are often used as a form of therapy or relaxation, as they are believed to help reduce anxiety, improve focus and concentration, and promote feelings of relaxation and well-being. They are often used in combination with meditation or other mindfulness techniques to help individuals achieve a deeper state of relaxation or focus.
While the science behind binaural beats is still not fully understood, many people find them to be a helpful tool for achieving a more relaxed and focused state of mind. There is ongoing research into the effects of binaural beats on the brain and the potential therapeutic uses of this technology.
