Binaural beats are not scientifically proven to improve sleep; the perceived benefits likely stem from the distracting or soothing effect of gentle sounds that calm the mind.

Matthew Walker highlights an important distinction here between the theoretical neurological effect of binaural beats and their actual efficacy regarding sleep. Current research, including meta-analyses on sound therapies, shows that while these beats may slightly influence the state of relaxation or pre-sleep anxiety, clinical evidence for a direct improvement in sleep architecture remains very limited and often contradictory. Numerous studies are small in size or present methodological biases, making a formal conclusion difficult. Walker's explanation regarding 'gentle distractions' is consistent with research on sleep hygiene: background noises (white, pink, or nature noise) function primarily by masking environmental sounds and reducing cognitive vigilance, which facilitates falling asleep. In short, the 'technological' or rhythmic aspect of binaural beats is likely less decisive than the simple ability of sound to create a secure sound environment. There is no solid evidence that the specific mechanism of binaural frequencies is superior to classic sound-soothing methods.
