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?

Then what?

We need experiment and we need to  discover some individual able to hear this hypothetical change...

But ridiculizing the possibility of sensing  this phenomena  is not a good point of departure for a scientific journey...

Speculating about this possibility is better and looking for some who experimented it and wanted to be tested a better one for sure...

But a test organized to ridicule someone or debunking him is NOT A TEST....And certainly not a rigorous scientific test created in good faith and by honest curiosity.....

Then "sunday skeptic of the scientism club" or children of James Randi or professional snake oiler hunters are not useful to science here...No more than religious zealot or marketings people.....

It is easy to understand....

A climate of trust only make thinking possible....And discovery possible...

Doubt is a tool not a vocation or a working field.....

Human need beliefs, and need doubts; but human need over all  to think and thinking process is  alway using these 2 tools simultaneously...

And it turns out that, for example, in a RIAA corrector, the error of the wire going from the MC head to the transformer will be amplified almost 1000 times!

Does not work that way. If the error is simply frequency response, the relationship between the perfect and imperfect signal never changes.

dletch2, you haven't finished explaining your previous statement yet:

"The interference of a power cable can get into the signal circuit and become audible not as periodic interference of 60Hz harmonics, but as non-periodic one so that initial frequency of 60 hz is perceived as something related to a musical signal (for example, frequency response), and not as interference or noise."

After you make this one clear, I expect the next explanation from you:

How the difference in frequency response can occur when a short piece of wire is reversed?

And please, no more muddy theories. You are required to:

1 - numerical or relative estimation of the level of possible interference
2 - numerical or relative estimation of the level at which the interference penetrate the signal circuit
3 - In what exact place it penetrates there the signal circuit

Ok now we are getting somewhere. Have you done that? Where are the results published for those who might be interested?

I have an article in Russian https://www.backtomusic.ru/do/radio/testing, there is a description of a lot of subjective experiments made using the testing system, but what can they give you, other than to take the topic aside?

I would believe whatever differences there are would show up most in cases where there is an impedance mismatch which is much more likely with zero feedback amps, but that should not really matter if one has addressed impedance matching between amps and speakers properly, which is the right way to do it for best results, so in that case impedance matching issues due to a zero feedback amp is a moot point.

That's a shot in the air, sorry. Whatever the impedance mismatch is, it will remain the same for any changes in the area of J1 and J2. It will not prevent us from conducting the experiment, all other things being equal.
mahgister,
to be honest, I did not think that in this topic I can learn something new to me, but you have already brought a lot of interesting information that goes in parallel with my audio practice. I am going to post some of your posts on my site. Of course, if you don't mind.

Regards
I never wrote only for you....But for the others readers ...

You have entered this subject years ago already if i read correctly....You know electronics not me....And you listen yourself to your wires,not me...

But i am interested by the consequences of this matter.... His meanings for philosophical research....

For sure you can do what you want with my posts...
