Neurochemical processes in human brain are measured by wave function which is nothing but Brain Wave. These waves are measured by EEG machine are indirect means of assessing of the mind consciousness. Depending upon consciousness level these are categorized into four frequency band as beta, alpha, theta, and delta waves depending upon activeness of mind. No single brainwave state exists but it is mix of all four and one is predominate at any given time. These waves are the outcome of binaural beat phenomenon which is the auditory brainstem responses originate in the superior olivary nucleus of each hemisphere. As even low-powered oscillations can have enormous effects on standing waves by resonance effect. This technique can also be applied to brainwave entrainment, where binaural beat can be changed through audio binaural beat resonant entrainment techniques by applying sonic frequency through stereo headphone. This paper reviews the use of this technique of consciousness management to alter the state of mind.
