But, what you get in this noise mish mash is not the various noise types independent of each other, and not really so much clusters of them separately, but it has been described as a weird sort of "elephant man" distortion of the original waves...like a blob of standing waves that changes shape according to environment influences, the dynamic power-related ones of how many circuits in the room (or home) are active, off, in sleep mode or are changing with the power demands of the music, the wifi, other usage patterns or what have you. It may also shift its size or location when you like open a door or move around in the room. IOW, RF **may**, I only say may, be piggybacking, to some extent, onto other energies in the room that Do have a charge.
The whole elephant-man blob, though, is looking for a path to ground. So it is attracted to anything in the room with lower resistance...your components, the in-wall wiring, anything metal and of course us - we are electrical. Perfect Path, Alan Maher Designs or whatever other quantum-based solutions going forward, will work on the same principle: to 'wick' away the 'blob' by providing a resistance that is lower than anything else in the room. This doesn't **completely** get rid of it, but it does plainly reduced that energy...the idea in general to reduce it inside the component, at the breaker box, the in-wall wiring, system wiring or wherever else it may be deemed advantageous, but note that where that idea points to in the end, is to effectively treat the whole home...even though for many people's particular performance goals, that would not be strictly necessary.
Technically, as I understand it, this is done by attracting the positive charge of the blob into the noise reduction filter or device, in which it exits the other side as negative ions. IOW, these are environmental scrubbers...just scaled down from the industrial smoke stack applications.
Graphene then, is not really the only material to be looking at for such a design. Highly conductive ceramics, high purity silver, gold or copper, nano-carbon fiber and anything else of very low resistance might be fair game.
