Why do I here the binaural tone in the background ?
Since the Programmed Binaural Sound is such a low frequency, some Mp3 players and/or earphones may not be able reproduced the sound at a sufficient level or quality to be effective. Therefore, we set the level of the tone to be slightly audible to assure that anyone using any quality of equipment will be able get the full benefit of Programmed Binaural Beat Sound.
