Can binaural beats affect arousal?

Yes, binaural beats can affect arousal. According to Andrew Huberman, binaural beats involve listening to sound frequencies that slightly differ for each ear, which can shift the brain into specific states. This modulation can impact whether you feel more alert or calm, depending on the frequencies used. However, it's important to note that the scientific data supporting these effects is not plentiful, and the outcomes can be subjective based on individual responses to these auditory inputs 1.
