Binaural beats therapy is an emerging form of soundwave therapy in which the right and left ears listen to two slightly different frequency tones yet perceive the tone as one.

The binaural auditory beat that a person hears is the difference in frequency between the left and the right ear and should be at frequencies lower than 1000 hertz (Hz) for the brain to detect the binaural beat.

For example, if the left ear registers a tone at 200 Hz and the right at 210 Hz, the binaural beat heard is the difference between the two frequencies — 10 Hz.

Researchers believe these changes occur because the binaural beats activate specific systems within the brain. An electroencephalogram (EEG) that recorded the electrical brain activity of people listening to binaural beats showed that the effect on a person’s body varied according to the frequency pattern used.

The four known categories of frequency pattern include:

  • Delta patterns: Binaural beats in the delta pattern are set at a frequency of between 0.1 and 4 Hz, which is associated with dreamless sleep.
  • Theta patterns: Binaural beats in the theta pattern are set at a frequency of between 4 and 8 Hz, which is associated with sleep in the rapid eye movement or REM phase, meditation, and creativity.
  • Alpha pattern: Binaural beats in the alpha pattern are set at a frequency of between 8 and 13 Hz, which may encourage relaxation.
  • Beta pattern: Binaural beats in the beta pattern are set at a frequency of between 14 Hz and 100 Hz, which may help promote concentration and alertness. However, this frequency can also increase anxiety at the higher end of the frequency range.

Benefits of binaural beats therapy

Binaural beats therapy is primarily used to treat anxiety and stress, although it may also improve concentration and motivation as well.

Potential benefits include:

  • reduced stress
  • reduced anxiety
  • increased focus
  • increased concentration
  • increased motivation
  • increased confidence
  • deeper meditation
  • improved psychomotor performance and mood
