What are binaural beats?

Binaural beats are sound frequencies played through headphones in each ear that can stimulate the brain to produce certain waves. Although this technology is relatively new, the concept of binaural beats has been around for over 180 years.

Binaural beats work by taking advantage of the fact that our brains can perceive and process sound waves. When two sound waves of different frequencies are played in each ear, the difference between the two frequencies is perceived as a new, vibrating tone. This new tone is called the binaural beat and has a frequency equal to the difference between the two original frequencies.

For example, if a 400 Hz tone is played in the left ear and a 410 Hz tone is played in the right ear, the binaural beat will have a frequency of 10 Hz. The difference between the two original tones of 400 Hz and 410 Hz is 10 Hz.

When we listen to binaural beats, our brain responds by mimicking the waves of the binaural beats. This phenomenon is called brain synchronization. Brain synchronization is the process by which the brain adapts to the frequencies of the binaural beats and is thus brought into a certain state.

There are different frequencies of binaural beats, each of which can have a different influence on the brain waves and therefore on our mental state. For example, binaural beats with a frequency of 4-8 Hz, also known as theta waves, can put the brain in a relaxed state and promote creativity. Binaural beats with a frequency of 13-30 Hz, also known as beta waves, can put the brain in a state of alertness and concentration.

Basically, binaural beats are a form of sound therapy that uses the properties of our brain to help us relax, concentrate and sleep better. By using the right frequencies of binaural beats, we can put our brain in the desired state and help us improve our mental performance.
