Your "Many Worlds" Audio System?

I fail to see what photon behavior has to do with an audio signal.

The double slit experiment encompasses electrons as well.

Ah, I didn't know that. 

Interesting, thank you.

Still don't see how this pertains to audio equipment or an audio signal.

Please explain the correlation.

From the first link:

"As it turns out, the Schrodinger equation does predict what will happen.  The wave will become entangled in the waves of the quantum objects comprising the measuring device.  It will become entangled with the environment, just as pilot-wave predicted, but unlike pilot-wave, Everett dispenses with the particle."

How Electricity Actually Works

My question is if electricity is actually a wave function then how might our measuring devices be somewhat deficient in assessing the electrical properties of audio components, wires, cabling, etc. and are these devices actually measuring everything that might impinge on "sound."

     Does this mean: there are actually some, on this site, willing to discuss how Quantum Mechanics might actually influence our listening?

      I'll repost some snippets, from previous threads, for the interested, while cooling the flames, I typically direct at the Denyin'tologists.

       ie: Inescapable FACT: No one understands exactly how electricity works.     

                         That’s why there’s so much Electrical THEORY.  

   

      The number of Wiki-Scientists on these pages, attempting to win the IG-Nobel Prize in Pseudo-Physics, is always amusing.             

       Whenever some highly educated person actually does discover exactly how electricity functions, they’ll be lauded by the scientific community, will have solved some of the disparities between Relativity and Quantum Mechanics, receive a Nobel and we’ll hear about it.     

      Newton’s THEORIES were largely superseded by Einstein and Bohr's.   Then came Feynman’s.       For now; none of you can absolutely prove your statements (theories), regarding electricity, fuses, wires, or anything else, as regards our systems. 

        In that last paragraph; my point is that no one knows exactly what/how to measure what may be occurring with the highly complex musical signals (lots of frequencies and changes in frequency, constant voltage/signal level variations, PLUS), though: they BELIEVE they can, based on the sciences of the 1800s.

             The following articles, read in sequence, illustrate my point:
