Binaural beats, simply put, are an illusion. What happens is when you listen to two pure tones separated into each ear, the tiny difference causes a “frequency mismatch” as the sound travels to the auditory part of your brainstem, says Hector Orozco Perez, an author of a recent study on the mysterious beats. Are binaural beats actually effective? Binaural beats in the lower beta frequencies (14 to 30 Hz) have been linked to increased concentration and alertness, problem solving, and improved memory.
