In the example, a binaural beat of 10 Hz would be produced based on the differing frequencies of 440 Hz and 430 Hz.īinaural beats originate exclusively from within the brain’s auditory system and are not a result of acoustic mixing of the different sound frequencies. These differences in sound frequencies will also cause the brain to create a new inaudible pulsating tone, approximately the mean value of the two initial sounds. When the brain processes these differing frequencies, an auditory illusion known as a frequency following response is produced, stimulating neural phase locking.įor example, if a sound frequency of 440 Hz is transmitted to the left ear and 430 Hz to the right ear, the brain will generate a sound with a middle frequency of 435 Hz. The results indicated that binaural beats significantly impacted the participants’ brain wave activity, demonstrating the potential for developing musical products that leverage the inaudible sound frequencies to affect human neural rhythms and states of consciousness.īinaural beats are a perception created by the brain when sounds with slightly different wave frequencies are fed directly to both ears. The study was conducted by a team of American researchers to explore the physiological effects of binaural beats on individuals experiencing stress and seeking relief.
A recent study published in Frontiers in Human Neuroscience has revealed promising findings regarding the ability of inaudible binaural beats to profoundly affect human brain function and induce states of relaxation.
