How Sleep Music Works?
When signals of two different frequencies are presented, one to each ear, the brain detects phase differences between these signals. Under natural circumstances a detected phase difference would provide directional information. The brain processes this anomalous information differently when these phase differences are heard with stereo headphones or speakers. A perceptual integration of the two signals takes place, producing the sensation of a third "beat" frequency. The difference between the signals waxes and wanes as the two different input frequencies mesh in and out of phase. As a result of these constantly increasing and decreasing differences, an amplitude-modulated standing wave -the binaural beat- is heard. The binaural beat is perceived as a fluctuating rhythm at the frequency of the difference between the two auditory inputs.
As a result your brain frequencies change to a relaxed awareness… welcome to the first stages of deep sleep.
Binaural Beat was discovered in 1839 by a German Scientist called H.W Dove
