Blind testing assumes that one steps in the same river twice

My ears and mental states change in the course of a single listening session. It's a matter of biochemical fluidity that affects or comprises the living subject. While relative to the listener, e.g., once it warms up, the preamp is relatively stable; in a way, listener and preamp are in different rivers. But non-blind testing adds a variable. And so is less reliable... or more reliable. What do you think? "Horse sense is the thing a horse has which keeps it from betting on people. " ― W.C. Fields |

Blind testing, like any testing, is not foolproof. Nt, posted on November 8, 2016 at 03:24:11 | |

that's where banned members like Mr. Voodoo, aka AJinFLA (Ammar Jadusingh) ended up along with guys like Arny Krueger. I read a couple of threads including selecting amplifiers and bass traps. Naturally, all "well designed" amps sound the same. :) Apparently, Arny is not one of Mr Voodoo's fans either. Even I've measured the benefits of using bass traps in my room. |

Arny: "Room treatments can effect such dramatic improvements that no DBTs are necessary... That may explain the surprising recent skeptical comments about room acoustics - the commentators are stone deaf and don't hear the natural differences in the acoustics of various rooms that the rest of us hear." Priceless. :) edit: I almost forgot to mention that jj is over there, too! |

Then one can be totally objective. You cannot hear any of it. |

"But if you do it with extensive tests and with correlation to objective measurements as Floyd Toole did over decades it becomes a very useful tool to go along with other tests. In fact Toole claims that doing both types of tests he's come up with over 95% certainty of predicting an excellent speaker. " Here's a video where Toole discusses this idea. The relevant discussion starts at 21 minutes 35 seconds. I can't seem to make that start time work with the youtube video embedding feature, so you'll need to fast-forward it manually to that point. Or you can use this link to go directly to the video on youtube at the right start time. Floyd worked out which loudspeaker measurements to perform (the so-called "spinorama"), and I believe it was Todd Welti who figured out how to process the data in such a way as to give a figure of merit having a high correlation with listener preference on double-blind listening tests. There's some more discussion and links in this post. |
Toole didn't design any Infinity speakers, or any Harman speakers for that matter (nt), posted on November 24, 2016 at 23:56:28 | |
