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?

i only express my view never play "drumbeat"...

What is a drumbeat?

It seems your post are more akin to a "drumbeat" here than mine....

Censorship and  scientism faith instead of experiment are your appeal not mine....

It is not about "cable sellers direction" in this thread but some way other many things....Then confusing the two to ridicule someone, this is a "drumbeat" for the crowds....

Enjoy....
The Junilabs Player and file optimizer is amazing. Waiting for the next version which he mentions would have more usability improvements.
@manueljenkin1,

It's a pity that Eric Juaneda from Junilabs ignores the questions. My friend asked him to explain the principles of file optimization or just say something about this interesting thing. He didn't answer.
In the meantime, I became convinced that there must be some non-physical explanation for the change in sound that we feel. It is strange but the only thing the optimization program does is load the file into memory, wait for a while, and write it back to the hard disk. At least that's what the programmer told me when he de-compiled the file and analyzed the code. Why this changes the sound of the file is unclear.

I've done some research on how people feel about the difference in optimized files. There is no repeatability here, some prefer original files, some - optimized, some non-audiophiles do not even feel the difference at all.

However, here we certainly have another confirmation that digital audio is far from perfection and audiophiles feel the difference in the sound of files with the same checksum. And there going to be some more then just conventional physics to explain this phenomenon.
