Binary Brains And Binaural Beats


This blog entry is further evidence that I'm not interested in writing the truth as much as I am capturing drifting thoughts with words, and in this case the drifting thoughts are about the binaural beats material I have been subjecting myself to for a few days.

My earlier study of binaural beats was revealed to be less-than-in-depth the last few days. I never have fooled myself that I had become an expert in this subject. As a matter of fact, my meager efforts to create binaural beats by my own bootstraps didn't work out because of technical incompetence. I made better than passing grades on the theory of electronics, but I was never able to get it from my head into my hands. I'll live.

Until I watched a video by a nerdy guy who does know how to create binaural beat videos I didn't really know what a "beat" was, much less that the definition would have informed me that it had to evince itself binaurally to happen at all. This guy not only explained the intricacies of binaural beats, but demonstrates it to his viewers who wear stereo earphones. Now, I know what the big fuss is about.

My friend Rainey came by for a visit and rudely interrupted the amazed enthusiasm I displayed in explaining how ignorant I've been, in the past, by tuning my ratty-ass classical guitar using "beats". He told me just to "Shut up and listen...", and I did. He demonstrated how two strings on the guitar are tuned correctly.

To do that he played the same note on both strings by traveling up the fret board to the second occasion. Then, he plucked the first string and quickly followed by playing the same note on the second string. If the reverberation between the two strings produced a warbling roll of a sound, then it was off-key. If it didn't make that warbling sound it was in tune. The warbling sound is what's called the "beat" and it's produced binaurally.

Furthermore, when I was about to comment on this remarkable phenomena, he told me again to shut up and listen, "The lesson isn't over."

"Well... Damn!"

"Shhh..., listen!"

The rolling reverberation of "the beat" pulsed one way if the second string was too tight, but it pulsed another way when it was not taunt enow. He seemed pretty happy with his demonstration, and he oughta be. After he finished "the lesson", he admitted that he had never heard it referred to as a binaural beat, and that he had never felt satisfied with his previous explanations of how he tuned string instruments. That all changed by the ti-me he finished "the lesson". Now he can write that novel that's gonna be his saving grace.

Andy Dolph is the guy's name whose video explains binaural beats. He creates videos that feature it, and has a free download he kindly offers to well-meaning people who wanna hear his handiwork here:

Taking the beat out to tune a stringed instrument is just as deliberate an act as introducing a binaural beat designed to entrain the listener's brainwave patterns to the desired end. In this case the beat can be shaped by the variation in the induced vibration.

I'm pretty sure the only precise result a normal person can get when they tune a guitar is the pure resonance of an exact match. My thought is that it might be hard to measure the exact distance apart the two strings are without a measuring device. This is not a problem with a digital signal generator. Precise frequencies can be dialed up from the git go with LED readouts galore.

Playing two digitally-produced pure tones simultaneously for the purpose of the difference between them is a piece of cake with the modern computers. The third tone rendered from the difference between these two pure digital sounds is the binaural beat. It can be adjusted to any other possible beat by changing either one of the pure sounds.

The point of producing a stereoscopic binaural beat is to simulate existing brainwave patterns such that the brain will entrain its current state of being to the induced binaural beat. What happens when it does that can only be extremely subjective. Like a bus ride, it gets you to your desired destination, but what you go there for is none of the bus company's business.
