A Brief Introduction to Binaural Beats

By: Dan Murphy

Binaural beats can have quite a few advantages for people. These advantages include such items as improving confidence, relaxation, aura viewing, help with addiction, increasing motivation and many more advantages. Over the years, you probably have heard of binaural beats and the associated advantages. Let us explore where binaural beats came from and find if they will work for the listed purposes.

In 1839, a person by the name of Heinrich Wilhelm Dove discovered the interesting phenomenon of binaural beats. When two auditory impulses ("tones") are played to both ears at once but are slightly different in frequency, the frequency difference in the Hz (hertz, or cycles per second) will be presented as what is referred to as a "binaural beat."

For example, let's presume that you have one tone being played to each ear. The one tone could be 180 Hz and delivered into your right ear, and the other tone could be 185 Hz and delivered to the left ear. The change in frequencies creates a "beat" referred to as the binaural beat. In the example, the variation would be 5 Hz.

These "beats" that are made will allow the left and right hemispheres of the brain to synchronize with the opposite side. These responses are not perceived by the ears; they are experienced by the brain only. The parts of the brain which the perceived responses are delivered from are parts of the brain stem, which are delivered from the superior olivary nucleus located in each of the brain's hemispheres.

The benefits have been found using binaural beats in hospitals and other similar environments in the recuperation process, as a substitute for pain medicine, to stabilize blood pressure, and more. Mostly, binaural beats have been promoted and marketed by an organization called The Monroe Institute. As a result, binaural beats are used frequently since they have displayed proven benefits on a large scale.

Three tapes were created and were given out to disprove or prove this idea in 1999. This study, conducted by Anesthesia, selected subjects that were involved in a varying number of procedures, gave them a tape with a product called "Hemisync," a classical music recording, or a blank tape. Each of the subjects were also administered a drug called fentanyl, which is typically used to assist with chronic pain. The subjects requiring less fentanyl were those not listening to the classical music recording, or the blank tape, but the subjects listening to the Hemisync tape.

Displaying that the benefits of binaural beats can be shown does help this sometimes misunderstood method. "Hemispheric Synchronized Sounds and Intraoperative Anesthetic Requirements" was done and greatly assisted in the promotion by explaining to the world that binaural beats are a benefit to the people that listen to them.
