What are binaural beats used in meditation? The sensation of auditory binaural beats occurs when two coherent sounds of nearly similar frequencies are presented one to each ear with stereo headphones or speakers.

The brain integrates the two signals, producing a sensation of a third sound called the binaural beat. Binaural beats originate in the brainstem's superior olivary nucleus, the site of contralateral integration of auditory input.
