Why Do So Many Audiophiles Reject Blind Testing Of Audio Components?


Because it was scientifically proven to be useless more than 60 years ago.

A speech scientist by the name of Irwin Pollack have conducted an experiment in the early 1950s. In a blind ABX listening test, he asked people to distinguish minimal pairs of consonants (like “r” and “l”, or “t” and “p”).

He found out that listeners had no problem telling these consonants apart when they were played back immediately one after the other. But as he increased the pause between the playbacks, the listener’s ability to distinguish between them diminished. Once the time separating the sounds exceeded 10-15 milliseconds (approximately 1/100th of a second), people had a really hard time telling obviously different sounds apart. Their answers became statistically no better than a random guess.

If you are interested in the science of these things, here’s a nice summary:

Categorical and noncategorical modes of speech perception along the voicing continuum

Since then, the experiment was repeated many times (last major update in 2000, Reliability of a dichotic consonant-vowel pairs task using an ABX procedure.)

So reliably recognizing the difference between similar sounds in an ABX environment is impossible. 15ms playback gap, and the listener’s guess becomes no better than random. This happens because humans don't have any meaningful waveform memory. We cannot exactly recall the sound itself, and rely on various mental models for comparison. It takes time and effort to develop these models, thus making us really bad at playing "spot the sonic difference right now and here" game.

Also, please note that the experimenters were using the sounds of speech. Human ears have significantly better resolution and discrimination in the speech spectrum. If a comparison method is not working well with speech, it would not work at all with music.

So the “double blind testing” crowd is worshiping an ABX protocol that was scientifically proven more than 60 years ago to be completely unsuitable for telling similar sounds apart. And they insist all the other methods are “unscientific.”

The irony seems to be lost on them.

That’s funny. Because I had no idea how cars work and so signed up for Auto Shop to learn. Every day the "class" was the teacher blathering some nonsense about maybe try and not skin your knuckles up too much today, I did that one time the wrench slipped boy did it hurt, yadayada blah blah freaking blah.

So I asked every kid there. They are all madly turning wrenches changing the carbs out and blathering banter. Not a one of them in the whole class the whole time had the foggiest idea how a car works! They were all monkeys with a hammer trying to fix a helicopter. Including the teacher!

So when I got a motorcycle and needed to tune it up I got a manual and learned myself. Two years later with a 240Z pulled the engine tore it down took it to a machine shop put it back together and it started on the first turn of the key, just fired up like it had never been taken apart. Even the timing was only very slightly off, because I had set it by eye very close which I was able to do because by this point I understand very well exactly what I am doing, how every single little bit of it works. All the stuff no one else was able to tell me about even in a class where that is supposed to be all they do.

If you want to learn this stuff the odds of running into someone like me who really does understand and can actually explain it are slim to none.

What that means is if you utter the words "double blind" in anything other than mockery and derision then YOU are the ape trying to fix the helicopter with a hammer. YOU need to drop the BS step away from the keyboard go out and DO and HEAR and LEARN- on your own.

I know it is scary having to actually do something. Yes it is a whole lot easier to jabber away on a keyboard pretending to know. But you know what? We can all clearly see that you do NOT know, because otherwise you would never utter the words double-blind in anything other than mockery and derision.
BTW have you noticed that all  of dletch2's posts have been removed ....at least from this thread. I didn't ask for it. Quite honestly I'm inclined to let people like him to continue to show themselves. If they don't self destruct they loose all credibility.

But then too, there are far to many measurebators with dogmatic opinions who have not developed the "agree to disagree mentality. No board can tolerate very many of them and we are getting more than our share. 
Its got everything you need and it measures well :)

Indeed ! Yes indeed !

Gosh its raining great lines.....that being said the clouds are parting and the sun is coming out....though, if history is any indicator, bad weather will be here again in short order.

i was in the presence of a true master race mechanic from a Japanese manufacturer with decades of experience. He taught my colleague how adjust the valve clearance on a particular engine. Simply spacing the intake valve tight to the gauge, and the exhaust a little loose gave a 30hp boost in output.

you dont learn stuff like that from testing nerds. You get it in the field trying, failing and learning.
