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


Douglas Self wrote a devastating article about audio anomalies back in 1988. With all the necessary knowledge and measuring tools, he did not detect any supposedly audible changes in the electrical signal. Self and his colleagues were sure that they had proved the absence of anomalies in audio, but over the past 30 years, audio anomalies have not disappeared anywhere, at the same time the authority of science in the field of audio has increasingly become questioned. It's hard to believe, but science still cannot clearly answer the question of what electricity is and what sound is! (see article by A.J.Essien).

For your information: to make sure that no potentially audible changes in the electrical signal occur when we apply any "audio magic" to our gear, no super equipment is needed. The smallest step-change in amplitude that can be detected by ear is about 0.3dB for a pure tone. In more realistic situations it is 0.5 to 1.0dB'". This is about a 10% change. (Harris J.D.). At medium volume, the voltage amplitude at the output of the amplifier is approximately 10 volts, which means that the smallest audible difference in sound will be noticeable when the output voltage changes to 1 volt. Such an error is impossible not to notice even using a conventional voltmeter, but Self and his colleagues performed much more accurate measurements, including ones made directly on the music signal using Baxandall subtraction technique - they found no error even at this highest level.

As a result, we are faced with an apparently unsolvable problem: those of us who do not hear the sound of wires, relying on the authority of scientists, claim that audio anomalies are BS. However, people who confidently perceive this component of sound are forced to make another, the only possible conclusion in this situation: the electrical and acoustic signals contain some additional signal(s) that are still unknown to science, and which we perceive with a certain sixth sense.

If there are no electrical changes in the signal, then there are no acoustic changes, respectively, hearing does not participate in the perception of anomalies. What other options can there be?

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...
The crawler does not need high reliability, and I have actually been involved in the development of products that went into space, and not once did anyone ever mention the direction of wire. Like never, not in many many meetings. Never in military either. Everything on the crawler would be very low speed by the way and not too high of precision. If there were concerns, it would be mechanical stress and they likely were not pulling off bare wire, but jacketed wire.

Most electricians have a fairly poor understanding of electricity and certainly cables in a technical sense. I hope that was not a plead to authority.
is this akin to standing downwind or upwind from your pal after a mexican dinner??? 🤭🤭🤭

there are times and circumstances in which directionality can be darned important!!!
