If that were true, why do the acoustic standards focus on the six octaves that

Dan, I already agreed with you that 8 KHz is important, and I wish I had that data. If I do a surface reflectivity test here of concrete versus wood, will you and others accept the result as valid? I have no idea what the result will be! But there's no point in my bothering if you guys will then find something else to object to.

Even when applied correctly in the right space, Sabine calculations rarely come near reality.

Again, I was and still am willing to test materials here. Then I can test pure reflectivity, rather than rely on absorption data from someone else. My fear is I'll go to the trouble to do this, and y'all will some up with some other reasons to dismiss the results.

So, are we all simply wrong?

I honestly don't know, but it's certainly possible. So far I have seen nothing but opinion. Indeed, for all the talk of "we demand scientific proof" I'm the only person who has actually done that.
Tell you what. All of you, not just Dan. Let's devise a practical test that you all agree in advance will be valid, no matter the outcome. It must be practical and possible! Not "Build two rooms" but something that can reasonably be achieved in a day or whatever. Then I'll do it here, and hopefully one or two others will do the same so we can compare results.
Deal?
