Binaural beats, created from two different sound frequencies in each ear, aim to synchronize brainwaves and induce various mental states such as relaxation, focus, or creativity. While there are various claims regarding their healing properties and physiological effects, many of these assertions lack scientific backing, and most documented effects appear psychological rather than physiological. Overall, binaural beats can influence mental states and may be beneficial for relaxation and focus, but their effects on the body remain inconclusive.
