Yes it dawned on me after getting all the images except A and F , that my blueprint/drafting skills weren’t allowing me to see anything other than how it was drawn......I wondered then if it’s hard for a EE to hear things that they were trained didn’t exist?
Where us ‘simple folk’ can hear it in different ways like those drawings.

Yes its hard for EE's to hear ghosts, mermaids and dragons. I sugest those that do seek help.
 
Some time ago in this very thread I reported a blind procedure to test oneself. All it takes is scrambling what is being listened to until you have no idea which sample is which. Its much like shuffling cards, shuffling them until they they are thoroughly mixed, then shuffle some more. Once there is no way you can know what you are listening to, then go ahead and test without looking. Learn from mistakes with instant feedback (which research shows is best for learning), and practice until perfect while blind. The procedure described above meets the technical definition of double blind so long as one, in the capacity of experimenter and in the capacity of test subject, has no idea which file is being listened to.

I'll take the bait again (yesterday it was useless with another similar claim, but what the hell...).

Please point me to the post where this plan test was described and confirmed to be valid by the almighty sensory tests gurus.

I often talked with (pop) musicians about this. Most of them are not at all interested in Hifi. Guitarists visualise the play of the fingers on the guitar neck of the guitarist they are listening to. Even the physical feeling of the chords under their fingers. Their minds seems to reconstruct the sounds they are used to.
P.A. sound engineers reconstruct the scene view from the mixing desk etc.
It is very difficult for a violinist to accept a convincing recorded sound of a violin, because what they are used to is the very different way their violin sound near their ears.
 
You didn´t tell the truth when redefining the "original message".

Come on, using the post in which he was sidestepping as "proof" that he was not sidestepping because the topic he wants to avoid wasn´t included is surely an innovative way of bending the truth. 😎

Friends of surrealism have to admire the effort......

A perfect example of what myself and others called "word salad". Here is the reality, whatever are you going to mishmash about.

just a product of their environment/training.......so in this case being uneducated could be better.
Ignorance is bliss as they say 😀

Wish I could find it, but the search function is not very good if you have tried to find things around here. Doesn't matter, I don't think in this case. The idea that one can test oneself blind is pretty plainly obvious. Its more an issue of actually wanting to do it, rather than figuring out how. I have done it, and so could you if you wanted to, and you know it.

As far as approval from anyone else, I didn't ask for any. I merely pointed out that it can be easily done and how I have done it.

...example of what myself and others called "word salad"

If you don't understand the words, just ask. Or, maybe you use the term 'word salad' to refer to anything you don't like hearing.

I've had this argument with Mark, is it such a great thing to be educated in hearing small differences (unless it's your job of course)? What if you find you can't turn it off and, I don't know, just laugh at the imaginary joke you thought Chopin just told. Personally I'm not prepared to take the risk

Nope. Here's an (pathological) example of word salad:

"Obey space cat disjointed languages swearing admit stranger bit dressing"

I am sure Jakob is appreciating your efforts to defend him :rofl:, but please focus in finding that test plan example. This would add some meat to the word salad and make it more palatable.

P.S. I now recall the Muppet Show illustrating more refined versions of "word salad". Also Monty Python's Flying Circus.

It would wreck the whole experience.......

We might become, oh goodness......we might become objective audiophiles!😱
 
You are joking of course, Mark, Jakob and Merrill have already explained how this has no value to them, and so it follows, should have no value to anyone else.

I think you know the above is a distortion. If I have other things I want to do then I will do what is a priority to me. Syn08 mostly is playing debating games on this issue, as are you. Why give him a test plan when most likely he will just use it for ridicule fodder? If there are things in it he doesn't understand the reason for, do you think he will ask with the intent of learning, or intentionally misinterpret to go on the attack?

Mark is exactly correct.
In nearly every research paper that I & Jakob have linked to there are examples of well designed blind tests & issues encountered in blind testing.

What Jakob & I are mostly saying on here is that perceptual testing is not the trivial matter that is often presented on audio forums

It seems that you don't like that & won't read the research which uses blind testing but instead want a simplistic answer like a single distortion figure. Sorry, but that approach is just as incorrect in audio electronic measurement & testing as it is in audio perceptual testing

I would assume you are not a native English speaker. Actually, I see some questions and comments about dacs from non-English speakers that come out somewhat like your exaggerated example, but as usual, you seem to exaggerate for tactical reasons, to put your opponent at a disadvantage. Can't compete in an online exchange otherwise?
 
As a change from the advertised program for light entertainment I am proud to report my eldest has got herself a PhD placement. Her preferred choice of sweden looking at quantum magnets didn't follow on so she's accepted Marseilles studying thin film optical coatings.



Normal service is now resumed.

None of concern. Please focus in finding that test plan example, that's all that I care about, at this point. The rest is noise of zero average.
