What do we hear when we change the direction of a wire?

I think the only possible way to understand the nature of sound perception is to focus on studying a short piece of single-core wire.

There may be something to that. It seems to me it is all down to propagating a field. The field starts with sound pressure waves in air. These pressure waves are a manifestation of the repulsion of electrons in the outer shell of air molecules. So even sound turns out to be electric fields.

In the same way, when we make a gramophone recording. Even though it is all mechanical springs and levers and horns still it all comes back to electron fields pushing each other around.

Probably in most wire there is something asymmetrical going on that inhibits the coherent flow of this field.

For sure it cannot take much. Searching through user reviews of parts like caps it is clear seemingly insignificant construction produces big changes in sound quality. These parts all measure exactly the same yet in many ways sound completely different.

Seems to me this is all down to their ability to propagate this field in a coherent manner. This idea is reinforced by things we can do that are "outside" the signal path, at least in terms of what most today consider to be the signal path.

The prevailing myth is current moves along a wire. Occasionally some will acknowledge the field around the wire. Hardly anyone seems to think the field itself is the signal.

Perhaps millercarbon, you could tell us where the current "moves", and what generates the magnetic field to complement the electric field.  I have the popcorn on. Give me a few minutes. People who don't read physics books shouldn't throw electrons.  [I am laying claim to that saying.]

One possible physical reason for directionality of cables is due to the direction in which the wire is drawn and voids and irregularities that result from the drawing process.

This is the closest explanation I’ve found that actually reflect what we hear..

The WAY the conductor is drawn through the die is EXACTY how a direction is placed on cable. If you look at the extrusion process the actual material lays like tiles, lapping over each other in a DIRECTION, much the way a roof is laid. Bottom to top.

GUESS what that same analogy works for a conductive construct like WIRE. Try placing a roof BACKWARDS from the top to the bottom, NOT bottom to top...

That lapping, how much O2, and the purity of the construct or an actual alloy for a conductor and the way it was FORDGED is WHY we have a crystal type formation. It crystal LIKE structure is conducive to direction, NOT ABSOLUTE.. It’s not or ever has been a question of HOW a conductor like OCC is made, NOW take advantage of the NOW KNOW increase in sonic difference BETWEEN one direction vs the other direction.

There is a physical reason for wire and constructs to sound different one way and not the other.. No different than in a fuse, IF you look at the wire inside a typical busman fuse, under a microscope, you will see the same tool marks in the thermal wire... It looks like flakes laying over each other much the same way a ROOF tile is laid.

Again this ain’t rocket science, but I’ll BET you good money that NASA used that technology when wiring up the shuttle, they looked at the cable and HOW the wire WORKED.. Nothing was assumed with 100 year old electrical tech.. It just didn’t happen..

Off the spool and under a microscope. James B of Ampzilla did it 50 years ago.. He KNEW cable and wire sounded different one way than the other... Why do you think he literally WELDED the power cable in place the RIGHT DIRECTION on his then and STILL famous NO feed back amps...

My brother is a retired electrician and BA for his Union.. He had the funniest look on his face when we listened a few times.. He could hear but NEVER thought about cable sounding different.. Measure all day long exactly the same. but sound different.. Go figure.. Smart guy too, he's my big brother.. simple as that...

How much?  I will take that bet gladly.

Oh we have another SMART SNARK.. ok smart snark, here we go..

Your wrong... I know for a FACT the remote used on the crawler to move the shuttle and all the Saturn 5 rockets was in fact wired that way..

Off the spool, looked at and assembled, that is the way ALL critical runs of remote cable USED to be made at Holt..

BTW every cable I ever made for the last 35 year, I respected the fact that cables can be made BETTER.. AND for 35 year I made field repairs with DIRECTION in mind.... It’s tough enough to work on DC much less figure out how to make it work over LONG runs.. Oh yes, it’s a lot more that just resistance when it comes to working on cables.. A LOT MORE..

AC is king, but the reality of that is, DC will drive MOST AC or high current electricians wondering HOW to fix a circuit.. I’ve seen it countless times. Just wiring a boat trailer or something.. LOL

Low voltage guys get it.. they really do... A trained electrician.. LOL My WHOLE family on both sides, electricians, mechanics, nurses and cops, there is the occasional lawyer and convict, but that’s the same thing ..

Right... Lawyers and convicts, Cops and convicts.. Same thing to me..
One didn’t get caught one was stupid enough to get caught.. No difference..

Still family.. LOL

Semi-Regards.. That's a 5 out of 10 on the regards scale.. So we're still ok.. For NOW...
