Ah yes, the famous "B&K" curve (Fig 5, page 4). Well over forty years old today, and still very valid. I'm one of those crazy guys that still uses this today, for final room tuning. Because it still works! Forget the awful "X-curve", and the uninteresting "ruler flat" curve, and stay with this. Because the way humans hear has not changed, and probably won't change. I have found that B&K curve tuning is an excellent compromise between the dullness of very flat response, and the over-amped "bass heavy" EQ that some people like. My philosophy is that control rooms should sound natural, neutral, and transparent, and with the B&K curve you get that. It just somehow sounds "right".
Of course, you can only do that with EQ if the room is properly treated already, to get all of the acoustic issues under control! It's no use trying to use the B&K curve (or any other type of EQ) in a room that has lousy acoustics. Despite what some manufacturers of "room correction" hardware and software want you to believe, it doesn't work. Digital tuning can only be applied to a fully treated room. You can't fix a bad room with EQ!

That's a very useful one. The introduction to acoustics at the beginning is really good, and easy to follow, I think. Simple clear, diagrams, and simple, clear explanations. Plenty of good wall, floor, and ceiling examples, too.
