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?

There will be ABSOLUTELY NO DIFFERENCE in the sound you are hearing if you reverse the direction of ANY wire.  This also includes fuses too.

Anyone claiming otherwise, as usual is the case here on this forum most of the time, is completely delusional and needs serious psychological and auditory help.

I know of a couple of very good doctors in both disciplines if you would like a recommendation :-)

Using a single tone sinewave to understand how people perceive music is crazy.

OP
Of course, this is crazy, but who here says otherwise?

"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'"
andy, your quote is about perceiving sounds, not music. Learn the difference.
The greatest problem for the  understanding experience here is linked to the Cartesian divide beetween  mind and matter...

Most people cannot understand psycho-acoustic phenomenon where music experience is distinguished  from sound experience anyway and correlated with it...

 And  among most of those who understand half of them dismiss musical experience to be a "bias" or an illusion....

Reality is more subtle than our own apes brain...

 Then we must educate ourself and training ourself....Experimenting ourself like the OP was proposing for his own discussion... If not experimenting at least thinking and listening the opinion and experience of those who did experiment.......
