For centuries, the universal language of music has been understood to have healing effects. In the last two centuries, humans have invented and utilized electronic music synthesis or the production of sound via transmission of electronic signals. Electronic music synthesis has given humans the capability to produce pure sound waves (i.e., sine, triangle, square, and sawtooth waves), introducing new ways for sound to be experienced. Research has shown that sound, principally pure sound, can have notable effects on physiological functioning. The method called binaural beats involves two sine waves, less than 1500hz and less than 40hz apart played, played in opposite each using stereo headphone. Binaural beat technology has been studied in terms of brainwave entrainment. This works by synchronizing brainwaves to the internal beat pulse created by binaural beats. Studies prove this has effect, but the degree to which it is effective for each individual has been debated. This research project will center around the effects of sound on the autonomic nervous system, specifically stimulation of the parasympathetic nervous system. My goal is to produce and test a more effective method of achieving desired results. Combining the binaural beat technology with heart-rate variability biofeedback, I hope to achieve desired results, altering brainwaves and moving the participants into a relaxed, parasympathetic state.
