Binaural Beat and Brainwave Synchronization

Although research into binaural beat actually began over 130 years ago, it has only been since the mid-1970s that a significant amount of attention really has been paid to binaural beat. Moreover, it has only been in very recent times in which binaural beat has become to be applied in a number of different areas.

Technically speaking, experts have defined binaural beats or binaural tones as the auditory processing artifacts which are apparent sounds which are perceived by the brain independent from physical stimuli.

To many people, this definition can be confusing and not easily understood. What it means in layperson’s terms is that the brain reacts in certain ways to the binaural beat -- as if it were reacting so something specifically physical. In fact, with the binaural beat there is no direct physical stimuli that is causing the brain to react. Rather, the brain is somewhat interpreting two different tones -- the binaural beat concept -- and reacting to these tones. For example, the binaural beat is used by professionals in helping their clients with relaxation techniques.

As mentioned, the binaural beat actually was discovered a long time ago. This effect, the binaural beat effect, was first discovered in 1839 by a researchers named Heinrich Wilhelm Dove.

One of the concepts in which binaural beat has played a role is that of brainwave synchronization. Brainwave synchronization which is also known as brainwave entrainment is defined (technically or scientifically speaking) as functional brain connectivity expressed as a deviation from the statistical independence across the events in distributed neuron groups which create brainwaves.

This definition actually is very complex and not easy for a person without a scientific background to understand completely. Indeed, from a layperson's standpoint this scientific definition likely makes little to no sense. With that understood, a less technical discussion actually will be helpful.

In this regard, binaural beat is utilized to cause a particular effect in the brain. By this it is meant that binaural beat is used to cause a response in regard to certain brainwaves. For example, the binaural beat can be used to effect the brainwave element that is most responsible to enhancing relaxations. Hence, the reason binaural beat techniques are now being more widely used by professionals involved in the field of relaxation for their clients or patients. Techniques involving binaural beat are also being used in meditative practices today.

The common thought amongst researchers today is the binaural beat will have even broader applications well into the future. Beyond being used as part of meditation or relaxation regimens, many experts believe that binaural beat will also have broader and potentially very significant medical applications. There has already been some research in regard to the interplay between binaural beat and a patient afflicted with Parkinson’s disease.
