Is this test done because blind people on average have better hearing ? I cannot find anything about that in the description.
This is only the second time I have had to deploy this emoji:

You must be jokingIs this test done because blind people on average have better hearing ? I cannot find anything about that in the description.
It's called that because "information which may influence the participants of the experiment is withheld until after the experiment is complete.."Is this test done because blind people on average have better hearing ? I cannot find anything about that in the description.

Guys. The member who asked this question is located in the Netherlands. Maybe it is a troll job, but much more likely that English is not their primary language. Be kind!This is only the second time I have had to deploy this emoji:
I did not see your analysis when I posted my comment. My apologies.That is not true. The ratings from this panel were significantly different for OSD vs KEF, OSD vs Revel and JBL vs Revel.
Ranked the same doesn't mean indistinguishableI did not see your analysis when I posted my comment. My apologies.
Based on what YOU posted, it seems that KEF and Revel are indistinguishable for this audience.
I still think it is rather dangerous to post conclusions based on a sample of 10. I would prefer to replicate the findings with a larger sample. Also, I would make sure you have representative numbers of "trained" versus "untrained" listeners.
To my cautious eyes, this is just an interesting observation and worth validating.
Your "overlap" comment is what I looked at in the original graph. If I look at the overlap graph alone as posted #80, the KEF and JBL are "trending" to be different, but I am not sure you can say they will sound different to other groups. There seems to be of little doubt that the OSD appears less preferred. If this is validated, then do the comparison with only the KEF, JBL and Revel to make sure.
@CtheArgie Could you please elaborate on how you arrived at this conclusion?Based on what YOU posted, it seems that KEF and Revel are indistinguishable for this audience.
82% of statistics are made up on the spot anywayBased on responses thus far, I am 95% confident that 15% of ASR members understand basic statistics and 90% do not.
2 of the 12 listeners did. The two of us that organized it knew the speakers going in--but we were careful to randomize it so neither of us knew what was what. I connected them all up and did the virtual routing and then covered them behind the blind. My partner then used a random number generator to randomize everything. Inside the software they were just labeled A, B, C, D--but he didn't know what was what. "Speaker 1" for Fast Car and "Speaker 1" for Just a Little Lovin were randomized, they may have been the same and they may have been different.
Car washing (detailing?) is such an apt metaphor because many find it incredibly therapeutic as they pull out their car washing kit with clay bar, spritzer, sponges and exotic waxes, etc.

I would be REALLY interested in the OP taking my earlier ABX suggestion and find out if listeners can reliably distinguish between the REVEL and the KEF in the set-up/configuration the OP used.Ranked the same doesn't mean indistinguishable
The scores are not significantly different. Thus, I don’t think that the panel could distinguish them. Alternatively, they were not different For them.@CtheArgie Could you please elaborate on how you arrived at this conclusion?
I still don’t get how would you want to achieve that. One is an in wall speaker, the sound is not coming from the same place, of course they will distinguish the two!I would be REALLY interested in the OP taking my earlier ABX suggestion and find out if listeners can reliably distinguish between the REVEL and the KEF in the set-up/configuration the OP used.

Plus, no one scored both equally, it’s a preference, the average is close, but some prefered the Revel, some prefered the Kef., there is just not a trend to say conclusively than one is prefered by most. I feel everything get’s mixed up when you say the word “blind test” it gets used to push all kind of theories that has nothing to do with the test. Let’s take the result for what they are, we’re on a science based forum.Logic error. Like @PeteL said. From the OP, "Participants were asked to rate each track and speaker combination on a scale from 0-10 where 10 represented the highest audio fidelity." Two speakers can score 8 out of 10 with two different "2 out of 10 shortfalls" -- it is not logical to say they are indistinguishable. If 2 cars score 8 out of 10 for good looks, does that make them indistinguishable?
Actually it is brave to publish the results with a small sample size. Hard to get significant results with small samples. The fact that there are 2 significant effects means these are very noticeable. To find subtle significant differences you want a large sample.I still think it is rather dangerous to post conclusions based on a sample of 10. I would prefer to replicate the findings with a larger sample. Also, I would make sure you have representative numbers of "trained" versus "untrained" listeners.
