People are right to be skeptical about binaural beats. It seems hard to believe that by simply putting on headphones brain state can be positively manipulated.
Moreover, where such a science exists there must be evidence, right? Of course.
We know that Heinrich Wilhelm Dove and Dr. Gerald Oster concluded that binaural beats had the potential to impact cognitive behaviour , but it has only been in the last 30 years that further research has taken their work further to discover that binaural beats brainwave entrainment can help control and cure conditions such as ADHD, depression and anxiety.
In 2007, an interesting study took place in the USA. The study assessed the psychologic and physiologic effects of binaural beats.
NCIB Binaural Beats Study
Carried out by the Helfgott Research Institute, National College of Natural Medicine, Portland, the study took 8 healthy adults and gave them a CD with delta (0-4 Hz) binaural beat frequencies to listen to daily for 60 days.
Psychologic and physiological data were collected before and after a 60-day intervention. In terms of psychology the study measured anxiety, mood state and quality of life, and physiologically the study looked at things like insulin and dopamine levels, melatonin and blood pressure levels over the duration.
The results showed a decrease in trait anxiety, an increase in quality of life, and a decrease in insulin-like growth factor and dopamine in all patients.
The results speak for themselves, binaural beats work. And used over extended periods of time the effects on quality of life, happiness, and general wellbeing are very real.
