In many fields of science, audio in particular, there is the discussion of polarities. It is no different in Beltist science. The nature of the polarities under study may not be the same, but in audible terms, they have a similar effect. Reverse + / - leads to one of your speakers, and you'll see what I mean by "effect". Incorrectly phased, there is a kind of "inverting" of the sound. It only sounds "right" one way. Some may readily discern an incorrect polarity condition better than others (might take practice), but all are affected by it. The musical message can be lost without it.

In studies of Beltism, polarity has a much more widely defined role. The founder of Beltism, Peter Belt, discovered the effects of polarity on human senses more than a quarter century ago. He demonstrated this to many visitors at hifi audio shows at the time, and through his products at PWB Electronics. For example, one product existed that consisted of a brush which would  produce a beneficial charge when used in one direction, and a negative charge when used in another ("electret brush"). By "charge" I don't mean static charge (though all Newtonian principles still apply!), but the influence the brush was having on energy fields that surrounded the object being brushed; and in turn, the sound produced in the room the object was in. Another demonstration at the time (witnessed by John Atkinson of "Stereophile Magazine"), consisted of the polarization of an LP disc, with the sound correct one way, and then sounding worse when the polarizing effect was reversed. In my post here called "All the leaves are brown", I give an example of this Beltist polarity effect using an untreated object that is commonly found in our environment: a leaf.

When referring to electrical polaritiy conditions that are functions of Beltism, rather than Newtonism (aka conventional electrical theory), I've coined the phrase "advanced polarity" to refer to this phenomenon. Let me explain what I mean by that. I think I first noticed the effect of "advanced polarity" a few years ago, while rewiring a light switch (120v NA standard). My sound was different depending on which of the two wires was connected to which terminal (in an NA light switch, the black and red leads can be connected to either terminal, the light will still work). With say, the red wire connected to one terminal, the sound was correct, and with the red wire connected to the other terminal on the switch, the sound was worse. This was a repeatable effect, but not an electrical (Newtonian) effect. A Beltist effect. In other words, the effect was purely on listener perception. That does not imply autosuggestion, but that it was affecting the sense of hearing. How do I know this wiring observation wasn't some sort of electrical interference on the AC line? Because what I was using to make the observation was a battery operated mp3 player via headphones. This MP3 player observation can be easily repeated by anyone willing to rewire their light switch (don't forget to turn the power off first!).

The next observation in advanced polarity came from AC plugs. This one is much simpler and easier to repeat, provided you have standard NA electrical system two-bladed plugs. I made the recurring and repeatable observation that when I had a device with a plug that did not have a polarized blade, and so could be inserted into the AC outlet either way, the sound of my stereo was better when the plug was inserted one way, then when it was inserted in the reverse way. To those who believe they can make sense of this by imagining any number of reasonable explanations for why the AC current going to my amplifier or CD player might cause an audible change in sound depending on which way its non-polarized plug is plugged in... did I mention the "device" I was plugging in was a toaster? And that the "stereo" I was listening to was my battery operated "stereo mp3 player"?

I predict that even if there was no power reaching the electrical outlet, this "advanced polarity" experiment of reversing plug blades would still produce the same effect. You can basically go around your entire house, no matter the room or floor you are on, and find anything plugged in who's plug can be reversed, and test your sound with the plug in either direction.  One direction will sound more "correct" than the other, and each time you correct the "polarity" of that device, you will incrementally and permanently improve the sound for every source of sound in your home. That's Beltism too.
