We don't need spend $$$ flying to Jupiter to figure out no Little Green Men there, even if we could be wrong with a non zero 1E-68 probability.
Reasonable conjectures are one hell of a powerful instrument in applied sciences.
Sometimes I like to make the stripes on the resistors face the same direction with regard to current flow, and like to match resistors by pairs, checking that their resistance values are closest to one another.
Whilst I don't work on human subjects directly*, yeah, the kinds of stats needed for finding the envelope of human perception is going to require some stupidly big N and very robust protocols (you'd want to run a pretty wide gamut of tests per subject, too, or you'll be unable to be confident that it's not error when you find someone on the tails of the distribution).
In other words, I agree.
On the other side, single-subject at-home tests with even *modest* control/protocol would provide a chance to make hypotheses. We just have hearsay right now.
* The center I work with does though, and the number of samples we need for our stuff unless we dig down very deeply to the point where the trials would last decades, is pretty staggering.
One of the few vinyls I have left, is one of those "picture disc" of Linda putting on a pair of skates. I had it hanging on the wall for the longest time...it's stored somewhere now.
I saw the very last public singing of Linda, well after her affliction she came down with, & it was a very sad affair...I wonder? could she not use this Autotune we all know...to "restore" her voice so that she can continue to sing? I think it a better thing to restore someones voice, rather than to prop up someones voice who couldn't sing in the first place.

I quit listening to Linda when she came out with "Heart like a Wheel" with only 28 minutes of play time.
I recently did informal blind testing with two headphones and three subjects in three sessions with no contact/discussion between subjects.
All three subjects came to the same result.
Granted, more subjects/experiments are needed to establish statistical validity but in this case the results doubtless would serve to confirm the initial finding.
'At home' tests can be a good guide prior to formal testing.
Dan.
well if your test was 'does glorp change a cheap headphone' then possibly. Doesn't suggest anything new has been discovered!
Dan, carry on if you want, but these guys are never going to accept anything they did not learn in class. They apparently refuse to use their ears, even if they might learn something new.
I would be ready to, but not from an already proven quackery source. The commercial success (or lack, thereof) is no indication of intellectual probity.
I agree with this as well as the rest. Thing is, what I am trying to point out is that if someone here calls for science, then they need to be consistent. If those same people hear someone else post that they heard a difference in their living room with some product and then argue that those people need to do a double blind ABX test, IN MY OPINION those same people can't then say a less than rigorous double blind test is OK. You can't have your cake and eat it too, as the saying goes.
It's a bit like politicians blocking all sorts of legislation on the basis of science and then blocking action on other topics where the science is clearly in support of action. They speak volumes about themselves.
I know I'll get lambasted for this post, but at least I'll have a chuckle when it happens.
My father taught me to always do that and he was a 'Radio and Radar' specialist on the ground and in R.A.F Nimrods.
Makes em easier to read when going in common directions and matching is S.O.P for pairs.
I am extremely willing to use my ears, and my ears only, with the exclusion of as many other senses as possible. Why can't you?
Trying to deal with drunks in a lounge, different methods are more appealing.
This is better than accepting anything because of failure to learn in class, or failure to attend the classes.john curl said:
Let us be clear: many audio snake oil claims are not merely unlikely, they are impossible (i.e. they would require a fundamental change in physics). The weak, foolish and sometimes amusing attempts at 'scientific explanation' by the vendors and their fans just show how impossible they are. Hence anyone who knows sufficient genuine science can simply dismiss them, and laugh at them (as in this thread). This will always be a source of annoyance and frustration to those who don't know enough science and so are tempted to believe the nonsense being offered. These people may even accuse the mockers of being unscientific, trotting out the usual claims about "we don't know everything, therefore we know nothing" or "science is always changing" or "true innovators are always laughed at" thus further exhibiting their ignorance about science.
I have much more faith in the truth of Maxwell's equations (and Fourier, and Kirchoff) than I have in the performance of my own ears. Some may misinterpret this as a sign of a closed mind; they are free to believe this delusion. Unlike most of you here, I actually have experience of challenging the scientific consensus (on an obscure point of quantum gravity many years ago) so I am certainly not limited to accepting what I learnt in class. A real scientist can usually recognise the difference between a genuine challenge to accepted science (which may turn out to be right or wrong) and the spurious nonsense offered by a crank or a snake oil vendor.
Is this an attempt to insult the great unwashed mass of villagers that now have become drunkards?
