Research and real life

You ask me whether or not research applies to real life situations. You don’t ask this question when “true experts” like Ethan use measurements to “prove” that early reflections cause audible comb filter coloration yet these measurements are totally irrelevant simply because they don’t take into account binaural hearing mechanisms, in particular binaural decoloration. You blindly accept this line of reasoning perhaps because it looks good on paper and it's in line with the general opinion.

That simple statement, which actually is Toole’s statement, is not unqualified at all. Read Toole’s paper, read my own literature overview, read the literature if you really care, then you are in a position to draw conclusions.

As for the anecdotal evidence you are so obviously favoring, in his 1998 JASA paper “Spatial aspects of reproduced sound in small rooms” Bech says the following:

“When the level of the [single] reflection was set to its initial level there was a definite perceived difference between the standard and the comparison stimulus. The difference consisted of a loudness difference, the appearance of a second sound source and a timbral difference. A decrease in the reflection level caused the loudness difference to disappear, and a further decrease caused the differences related to the second sound source to disappear. The difference in timbre was the last to disappear, which means that the threshold of interest in the present experiments was reached while the timbral differences still existed. This means that the chosen experiment should allow the subject to discriminate between two coexisting cues.”

Bech takes this situation into account by using very specific investigation methods. Those folks who report on "improvements" when applying reflection treatment are not using any experimental method at all, yet you are sure that they are capable of producing meaningful results.
