If they want "proof", simply connect an EEG and measure the brain activity. Here is an anecdotal experience of how DBT fails when clearly the brain activity has changed.
[snip]
I can give thousands of similar stories.

Of course you can provide lots of similar stories, but unfortunately none of them have anything to do with DBT. Your story shows that a guy bought a new toy, hooked it up to his stereo that he hadn't listened to in years, and, mirabile dictu, liked it! *shrug* It would have been far more remarkable if he had not liked it. As for EEG, while I look forward to seeing your test results, I don't think they will show much of interest unless they show a change in brain activity in listeners in controlled double-blind conditions who also report hearing no difference. That might be interesting if you can consistently connect the change to a "sound" difference which is not consciously audible. Of course, emotional responses to "inaudible" infrasonics have long been known, so that's not exactly newsworthy either.

Unless you plan on doing intracranial EEG (not recommended...definitely, definitely not recommended), I think any results you might achieve are from a fishing expedition into noise (if you look hard enough, a pattern can be found :D). Actually, probably even *with* intracranial EEG...

It, like fMRI, is a pretty blunt tool. A lot of papers in this part of the world (fMRI/EEG) are kind of painful to read because they attribute too much to some variations in firing sequences and blood flow, and the public-at-large's reaction to horrid press reports about said bad papers are a couple orders of magnitude worse.
 
For all you "scientists" too lazy to click on the link that KBK provided, here is just the first paragraph of one link:

(Phys.org)—In a quantum superposition, a quantum object can be in two incompatible states at the same time, which is famously illustrated by Schrödinger's dead-and-alive cat. Recent research has shown that it's possible to have a superposition not only of incompatible states, but also of incompatible orders of events. We often think of events occurring in a definite chronological order, with event A happening (and causing) event B, or vice versa. But in certain quantum processes, events don't happen in a single definite order, but instead both orders (A before B, and B before A) occur at the same time. This counterintuitive superposition-like phenomenon is called "causal nonseparability."

I love when people not having the foggiest clue about quantum mechanics are calling quantum mechanics in support for any BS they conveniently accept.

It would help reading Susskind or any other similar book, at least for a basic understanding the complexity and the intricate world of QM. Once the basics are understood, it will become clear there's not much mystery in "quantum entanglement", and that "QM paradoxes" are only coming from attempts to interpret QM through our human intuition, or from mixing up classic mechanics with QM.

Flashnews: QM does NOT contradict causality.
 
Charles, good to hear from you. Of course, I agree with you. We could never make better audio products IF we relied on DBT almost exclusively. Yet, we can make better audio products if we use everything in our experience and trust our ears. Many of these people just don't know what you or I do to get the best audio quality, and they are not about to learn.

Yes and folks conveniently ignore interviews with the very physicists doing the experiments and their exasperation at the exaggerations and extrapolations of the popular press.

The behavior of a small ensemble of fundamental particles trapped in multi-Tesla fields at cryogenic temperatures has little to do with audio. The double slit delayed choice experiment does not either nor does not violate causality.

Why limit yourself to *just* audio?

Reminds me why I'm a fan of Feynman's intellectual humility. (Shared by many others, to be fair)

Hi Ed,

If you've not already seen it, this is a good presentation:

What passes for "science" today is completely broken. I recently saw a two-part BBC documentary on Quantum Physics. The first part was entitled "Einstein's Nightmare" and showed how they proved quantum mechanics is correct. Einstein refused to believe it ("God does not play dice with the universe."), but he was wrong. Physicist John Bell created a simple equation to prove whether quantum mechanic is correct or not in the early 1970s. It took another twenty years before they had the technology to run the experiments, but now we know that quantum mechanics is real.

The second part was how all of life (including photosynthesis) is based on quantum physics. There was a segment on "The Quantum Nose" that shows our understanding of how the nose works has been completely wrong for nearly 100 years. But they didn't even mention the guy who figured it out, Luca Turin:

The Secret of Scent: Adventures in Perfume and the Science of Smell: Luca Turin: 9780061133848: Amazon.com: Books

In Turin's book he describes how he had to undergo Schopenhauer's Three Stages of Truth. Stage One - he was publicly ridiculed in Nature magazine! The editor-in-chief commissioned a paper "proving" Turin wrong and even wrote an introduction dismissing Turin's work, proclaiming how it was his job to expose the "nonsense". ("Good" robot skeptic.)

The hilarious part was that the person who got the credit for Turin's work in the BBC documentary was just a tool of the machine. She created an elaborate experiment and trained fruit flies to be attracted to certain odors so that she could "prove" Turin's work, untainted by "human bias".

Yet stop and think about it for a second to see the irony here. Why would she spend several years an hundreds of thousands of dollars training fruit flies if she herself didn't smell any difference? Obviously she must have smelled the difference herself or she wouldn't have designed the experiment, applied for the grant, runt the experiment, and published the results. Yet it was all a ridiculous waste of time. She had already smelled the difference herself!

To satisfy the "skeptics" she had to spend hundreds of thousands of dollars and years of work. Anybody could have smelled the difference, just as she did. Then she gets the credit for Turin's work.

We have the same thing in audio. Anybody who cares can hear the difference between whatever - wires, connectors, PCB materials, amplifiers, CD players, capacitors, et cetera. Yet the "skeptics" demand "scientific proof". Then they ridicule those who can hear the difference - Stage One. Yawn.

. . . And this from the guy that calls IC's 'dirty bits of sand' and claims he can hear the difference between ebony cable lifters and oak ones.

Yawn indeed.

Bonsai, give it a break, will you? Charles and I have tried almost all audio quality IC's for suitability. It's part of our job. We just look DEEPER into potential sonic quality IC problems than most here, and often have to reject them. Sometimes we design them in, like I did with the AD712, and sometimes then we have to design them out, due to subjective or even objective conclusions after the fact. You guys would stubbornly keep with something that has been found 'fatally flawed' just because you can't understand how why a particular IC could even make a difference.
