Binaural beat therapy is an emerging form of sound wave therapy. It makes use of the fact that the right and left ear each receive a slightly different frequency tone, yet the brain perceives these as a single tone.
The purpose of using binaural beats therapy may differ among individuals. Some people may need help decreasing their anxiety, while others might want to increase their concentration or deepen their level of meditation.
Proponents of binaural beat therapy suggest that the potential benefits include:
reduced stress and anxiety
increased focus, concentration, and motivation
better long term memory after exposure to beta pattern frequencies, according to a 2019 study
enhanced psychomotor performance and mood
Some people believe that once binaural beats introduce a new frequency to your brain, your brain waves feel compelled to sync to it, effectively launching you into a different “brain state.”
Your brain has five different types of waves. Generally speaking, low-frequency waves are linked to “delta” and “thetaTrusted Source” states which can boost relaxation and improve sleep. Higher frequencies reportedly boostTrusted Source your brain waves into a “gammaTrusted Source” state which may make you more alert, focused, or better able to recall memories.
Mid-range frequencies have been linked to attention. Your brain moves into an “alpha” state when your focus turns inward (as in meditation) and a “beta” state when your attention is tuned to the world around you.
