Your "Many Worlds" Audio System?


Your "Many Worlds" Audio System?

And trying to measure it.

bolong

At least you ask questions...

Most people dont ask any and they hate those who ask some...Beware.. ūüėä

 

Audio measurements are useful to couple the gear with other components in a synergetic compatible way... Only narrow mind with no concrete training in acoustic could think that quantitative electrical measurements will indicate what they will hear as not only "qualities" of an audio system but "qualities" of the musical acoustic experience ...

The software engineering of files is not acoustic...

The recorded acoustic of a piece of live music is made of trade-off that will be TRANSLATED in your room by other acoustical trade-off of your own making... The audio gear CONVEY the signals more or less transparently thats all...

Acoustic matter more to understand audio and his link to musical experience than the electrical design of the gear...

Are the advocates for the primacy of audio measurements for things like cables and wires actually measuring runs of music streaking through the conductors, or are they measuring simple signals?

I have seen graphs on this site purporting to show mirror symmetry between music signals from cheap audio cables versus more expensive ones, but zooming in on the graph actually shows no such symmetry. This brings to mind a big question for me - how granular are these measurements?

      Some excerpts, from my post to a recent thread (>1000 posts), that became so contentious, it was deleted.

                                           DISCLAIMER:

    I left that thread, a couple pages prior to deletion, so: not my (direct) fault.

        At the very first mention of something as simple as Wave Function (a BASIC tenet of Quantum Mechanics), the Cargo Cult will label you a KOOK.

        But remember: they can only view/understand you, based on their limited experience, education and BIASES.

         They have overlooked the fact that, if not for the hypotheses/theories and experimentation, regarding Quantum Mechanics: a plethora of modern conveniences, medical devices and the gear they so love, would not exist.

          Had scientists, chemists and inventors shared the doctrines of the Cargo Cult (Denyin'tologists), there would be no semiconductors, computer chips, LASERs, or Magnetic Resonance Imaging devices (MRIs).

                                         Solid State amps?

                                     OOPS (back to tubes)!

                                        Your Smart Phone?

                                        FA'GET ABOUT IT!

                                         Your car's GPS?

                                                NOPE!

      Bring up those pesky details, regarding the likes of QED, Dielectric Absorption, Poynting's theorem and possible application/effects, relative to frequency, that our musical signals are carried via photon or wave, outside the conductor, always from source to load and you're a KOOK?

         Again: the Cargo Cult can only understand anyone with an actual background, experience and education in Physics/QED, based on their beliefs, education, experience and biases

                Oh well- let 'em go build another runway!

           Einstein got that last one wrong (Quantum Entanglement), BUT- I still wish he'd been alive, when the Hubble Telescope proved, what he considered his, "greatest blunder" (his inability to bring symmetry to his field equation, without lambda).

Another example of a hypothesis/theory, with no way to EXPERIMENT/MEASURE, what you're sure must be there, in some detectable way, or another.

                                            Happy listening!

 

     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:

 https://www.thegreatcoursesdaily.com/how-einstein-challenged-newtonian-physics/     

      then:

  http://hyperphysics.phy-astr.gsu.edu/hbase/Forces/qed.html#:~:text=Quantum%20 electrodynamics%2C%20co....               

       and: 

https://bigthink.com/hard-science/an-updated-feynman-experiment-could-heal-the-rift-between-quantum-mechanics-and-general-relativity/

 

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."

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.
