Electrical circuit "noise"


I suspect a few of you might find this post of interest regarding “noise” in cables and audio gear. I am on the Board of Directors of Verdigris Technologies, if any interested it is an AI company for managing electricity (www.verdigris.co). We got our start by recognizing that anything plugged into an electrical circuit, not only draws power, but also emits a rather unique signature back into the electrical circuit. The challenge is that as multiple electrical appliances are plugged into a single circuit, the signatures are all jumbled together. We developed unique technology that enables us to disaggregate all those jumbled signals to identify exactly which products are plugged into a circuit, and even identify early warning signs of failure, and we have patents regarding this technology. My point in all this is that it is clear that anything plugged into a circuit carries these multiple signatures from whatever is plugged into the circuit into any audio equipment plugged into the same circuit, and it is logical that at some level the garbage noise is is audible. So I think that it matters a lot how electrical power is managed, and that includes the cables used at each step of the audio food chain. Many of us don’t have the ability to have a unique circuit for just our audiophile gear, which is probably the best alternative, and so need to rely on products like regenerators and cables that reject noise to attempt to clean up and eliminate these unwanted garbage signals.

Well said. Yours is the first I have seen of anyone objectively analyzing this down to the level of being able to detect devices on a circuit. Makes total sense. 

Probably many different things are going on all at once. AC current starts to flow, but being audio never in a continuous steady flow, so it hits any connection or device there is an impedance shift and a wave reflects back. That is just one. Then the device whether it be brushes on a stator like your air conditioner pumps or diode switching in a component it probably emits another different wave going back into the line. 

All kinds of things like this. As you say it is one thing to detect and prevent a failure, quite another to listen and analyze in order to determine which of these various noise sources does what in terms of sound quality. Then maybe we find out one sort of noise flattens the sound stage. Just guessing here, a total for instance, but if we knew that then maybe we could design something tailored or focused to do that.

To think of just one possible application.

Great stuff. If you knew the stuff some of us are using, I could hook you up with someone you could really do some great work with. Seriously.
I’m pleased to see that someone is looking into this area.
Being "old school" I’ve always looked sideways at claims made by Monster and everyone that piled on afterwards.
"Oh please, You’ll claim anything to part folks with their cash"
That original attitude of mine has given way over the years to at least listening, if not always agreeing, with claims made.
When I saw dual RCA’s hit the market at $100 or more I cringed....but they were, at least, made of better stuff than the Radio Shack equivalents.
Still, seeing 6’ HDMI jumpers lister for $6,999.00 does little to make the point that they’re doing anything useful for the end buyer.....
That’s simple greed (It has to be....Right?’)
I found an AVS-2000 voltage stabilizer in the electronics trailer at our town landfill a few months back. ....thought I was going to give myself a hernia...tightened the 2 screws that secure the variac wiper (the only problem) while I like the readouts (voltage makeup, currant draw and output voltage) I can’t really say I hear any diff with or without it, to be honest though I’m not running 4 bridged Levinson amps or anything close.
All that said, I really enjoyed your original post and I think I learned something, which after all is the point of reading anything technical.
Thanks again,
Kevin
