scientific double blinded cable test

It can’t be that difficult. Pharmaceuticals are tested that way. Either something works comparing to placebo or not. And the variables are really complicated there. We bring people to the same room with the same high quality sound system, set of recordings and procedures agreed by a venerable audio society. We have our control cable, placebo, something off the shelf. We compare to it other cables with the same L, R, C. We ask testers to judge the sound reproduction accordingly. Neither experimenters nor testers know whether tested cables or control are used. If the results are near 50/50 then we know that if L, R, C are the same, no other variables matter. Pure physics. Bob Carver did it with amps, surely somebody must have checked it with cables? 
Then of course another study could be done how cable  L, R, C influence people’s judgements. And how expensive, or not, is tuning those three parameters.

At NASA there is a strict regulation to observe directionality of cables. Otherwise
false discoveries could result like that at CERN where some neutrinos were faster than light.

Hi @nugat

And are the cables NASA uses where they must conform to strict regulation to observe directionality used as audio speaker wire?



Ehmm....I would hope people get the NASA joke. 
I asked a simple question in the beginning and people gave answers 
to questions I did not ask. Perhaps there   was never a scientific double blind test of audio cables conducted.  I learned here how flawed science is, even trying to find objective truth. Well, instead we have post-truth  tweeted  to the whole world. People have not only own opinions but also own facts. NASA never flew men to the Moon, BTW.

Cables are not about soundwaves and hearing. Loudspeakers, rooms
and brain+ears are. Cables are about carrying voltage that tells loudspeakers how to move air. Amplifiers generate the voltage and cables are supposed to carry  it as faithfully as possible to transducers.
That process can be a subject of scientific research. What goes into the cable and what comes out. People and their ears are redundant here. Really nobody has done it in the whole world?

Of course BS, I explained above it was a joke about directionality of cables. Another telling feature of those exchanges is that people often read only their own posts.

„People and their ears are redundant”. Half-joke in response to claims here that double blind method  cannot study human behavior. So eliminate humans.
But in fact, if you check for error rates of digital transmission in cables the observer’s opinions are irrelevant. The same you can do with „voltage transmission”. Of course pundits here will claim that there is no method to reliably study human hearing which is quantum phenomenally more sensitive than any measurements.

At the end of the day everybody is entitled to pay for his Veblen goods. 

Here's a 1 cent challenge for all of you. Point to one business / professional area (science, communications, pro audio, IT, cryptology, military, medicine, power, space exploration, aviation, etc)  where cable directionality is a technical standard. Link that standard, please.

[cable directionality]

"It’s not a concern for their* particular forms of use." 

"Cable directionality" must have some physical manifestation, even if it's at quantum level. The "good" direction must be consistently  more effective in energy/information transmission. Otherwise it's distortion which cannot be "good"(local entropy variable) . Energy/information transmission efficiencies mean lives can be lost or saved and money made. One would think this could be of concern.

*all technical civilization based on electricity, except : see below


@geoffkait 
[cable...]

"...directionality is sound related only"
 

So  only some select  audiophiles can measure with  their ears  local entropy of cables conducting electricity? This skill or knowledge is not available to anybody else and no instrument can match human ears?

You "get it". So you agree: no cable directionality ;)

I always knew you were a man of reason (and ♡). Now let’s debunk together
the superiority of some audio cables myth.
Nugat out.
