Binaural beats are created by varying the frequencies of tones played to opposite ears. Setting the frequencies so that the difference is correlated with brain frequencies has been argued to affect people’s state of consciousness.
The system listens to a heart rate by a transmitted audio signal coming from a wireless stethoscope. The heart rate is analyzed and the tones are spaced in order to influence a more relaxing mental state – towards theta. The binaural beat frequency continues to be reduced as the person relaxes.
