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?

Hi, I really enjoy reading the comments in this thread, but as noob here I felt intimidated to answer. I was thinking of this story about wine, when suddenly people started posting about wine and Riedel glasses, so I felt empowered :)
While reading this thread, something seemed off in my system, as I've been playing around, experimenting, as a noob audiophile would do. Then I checked my interconnects, Van Den Hul 102something, and they were plugged in the other way around. There's a sticker where the earth is, that should go to the source, yes, a grounded reason :)
Felt better after reversing.

My good friend and I had a favorite wine bar downtown Budapest, and we went there quite often, tasted almost everything on the menu bar the most expensive ones. They served by the glass, exclusively in matched Riedel glasses. One day I got a French wine, way above our usual budget, we drank it at home (from my friend's Riedel glasses) then went down to our favorite bar and ordered our favorite wine. It tasted way worse than we remembered. The first time I tasted wine I wanted to spit it out it tasted so bad. It's an acquired taste that gets more refined the more you taste. Unfortunately, once you taste good wine it's difficult to drink lesser ones, though possible, they don't give you the same satisfaction. I think something similar is happening when listening to music. As I kept replacing components, putting on acoustic panels, I kept hearing more and more details, but also more and more flaws. I believe the more accustomed you get to a certain level the more you realize what's wrong or what's missing, with other words, the more transparent the system and the more used your brain is to a certain quality, detail level, the easier is to spot problems. When I first installed my 4k total worth of gear I was amazed at how splendid the sound was. After a few weeks, it started to sound wrong. I started to notice the room reacting, the standing waves, the whole cacophony. One by one I replaced everything with stuff costing 5x or 10x, and I noticed the difference. I even went back to changing components to make sure I wasn't a total tool.

When we go to sleep our ears and still hear the noises around us but our brain has a clever filter/firewall that enables us to sleep. It blocks the familiar noises so we can relax. However, if there's a siren blowing we will wake up, as we know that's the sign of danger. Sirens have been around for a few hundred years or less. Evolution taught our brain what's relevant and what not. We moved to a new apartment, near train tracks, first few days/weeks were a bit unusual but we got used to it, now we can sleep through the night, though the trains are still going on time.

I can easily imagine that originally our ears (and maybe bodies) are capable of picking up a much wider frequency spectrum than the current science considers de facto, but due to our planet getting noisier our brains just filter things out in the conscious domain (as proven by scientists). It could be that our brains go into a different state (alpha or theta) while listening to music, it widens the acceptance of frequencies which enables our brain to sense or perceive something different. And that could be the point where traditional science fails to answer, especially if it starts with the well-known and accepted theorem that humans' audible spectrum is 20hz to 20khz.

In my opinion, doing double or triple-blind tests with something that's an acquired taste won't provide scientifically sound results. I think if we really wanted to have a successful test we would need a huge group of people participating in a 3-month boot camp, listening to the same systems and songs until they start harboring suicidal thoughts, and maybe after that it could prove something, though probably just barely and it would raise more questions than it answers.

Going deeper in psychology, who we are is based on our DNA, our experiences in life starting from being in the womb, growing up, becoming aware, spending time learning things that interest us, and deciding we don't want to change anymore, what we know is a fact and we're fine with that. Or maybe we do and then we question everything, starting from the very first experiences to the directions of cables.
Sorry for not using quotes, there's too much, I will try to just write my thoughts.
If we accept the theory that homo sapiens emerged around 300.000 years ago, and Hertz came up with his theory about 120 years ago and was officially accepted/adopted ~60 years ago, it's quite a young theory compared to mankind. And if everything we scientifically know and measure is based on such a young theory there could potentially be things we don't yet know or understand. As every generation thought they knew everything there is to know and proven wrong time after time, we could experience the same, maybe in our lifetime. It's more like a thought-provoking exercise, not an assumption nor stating facts.

Regarding the acquired taste concept, I believe it's true to wine, food sound, and other things. It's the phenomenon that you don't know what you don't know. I didn't know what was hidden in music while I was listening on simple headphones or speakers in a room full of reflections.
As I started to optimize, get more resolution, more clarity, got rid of some reflections, I started to hear things that were not there before. If some soundwaves cancel each other out you might not perceive them. If some equipment colours the sound, or simply doesn't have the capability to transmit it to your ears, you won't know about it. But once you hear it once you will miss it if it's not there anymore. Same as with food or wine, or with driving a fast car. When you go from 50hp to 150hp you feel the wow effect, then you get used to it and you will miss the power if it's not there. Once you taste really amazing food, you will miss it when you go back to salt and pepper. If you try really amazing wine you will notice the difference when drinking a simple wine, even though it might please you just as much. But to know what you don't know you need to experience it first. So maybe, there is something science cannot explain but you can feel it, once the environment is prepared to reveal it, when your system and listening room and your own experience reaches that point, maybe the direction of a cable can make a difference. Maybe science did not discover everything there is to discover. It usually starts from the point that is considered and accepted as the non-disputable truth, then works from there. But there many theories which someday might be challenged, it's all relative in the end :)

I think a blind test using one's own equipment if the person is open-minded, self-aware, and critical, could work, it would also imply using a wire which is built exactly the same, except the actual direction, meaning no ground on one side of the connectors and no special electronics etc., that obviously skew the results, just simple soldered connectors. 
At least we're getting closer to why everything sounds better at night in complete darkness:

Besides, every particle resonates: https://en.m.wikipedia.org/wiki/Resonance

Can two cables even be the same? Is there a way to create an exact atomic structure, either left to right or right to left. What if you go to a deeper level than electrons? What if with time the structure aligns in a certain direction due to the constant flow and excitement of the particles? I think there's more to it than pure electrical signal that we can measure. Just some thoughts
