What are Binaural Beats?

In this post I introduce to my readers the concept of Binaural beats and its beneficial uses for humans. I effectively use it for meditation and for what I have repeatedly called (in my earlier posts) programming the sub-conscious.
Binaural beats were discovered in 1839 by a German experimenter, H. W. Dove. The human ability to hear binaural beats appears to be evolutionary adaptation. Humans possess the ability to detect the subtle phase shift of sounds arriving at one ear slightly before arriving at the other ear. This phase difference normally provides directional information and is what enables us to determine the physical location of a sound. The difference in phase relationship can be detected when sound frequencies are below approximately 1000 Hz. It is more difficult for us to determine the physical location of a high pitched sound.
The sensation of binaural beats occurs when two coherent sounds of nearly similar frequencies or phase relationships are presented, one to each ear and the brain detects phase or frequency differences between the sounds. When presented with stereo headphones over a period of time, the brain integrates the two signals producing a sensation of a third sound called the binaural beat. The binaural beat resulting in the brain is the phase or frequency difference between the two sounds.
Because the binaural beat is the result of the phase or frequency relationship of the two sounds, the binaural effect is produced regardless of the relative amplitudes of the tones. A slight hearing loss in one ear does not reduce the effectiveness of binaural beats.
Specific Binaural frequencies when heard helps in meditation, awakening, sleeping, quit smoking, increasing alertness, generating creative thoughts, and other such positive effects on the human mind. In the subsequent posts, I will talk about the effective uses of Binaural beats.
The above may appear too technical. Yes it is. But wait for my subsequent posts on the topic to understand the practical uses of Binaural beats.
