Super interesting stuff.  Dr Toole goes into detail about how they (Harmon) correlated objective test data with listener data and the test methods used.  Well worth the hour long view time as much of what is discussed can also be applied to headphones and personal audio.

Finally got around to devoting the necessary hour to watch this. Absolutely fascinating, and beautifully presented, and, what I expected to be hard work was a very pleasant hour.

Really fills in a lot of holes in my [lack of] understanding of room/speaker interaction, for starters, but the biggest thing was seeing how the measurement and cold science really goes hand in hand with the touchy feely stuff (well, not too touchy and feely, of course, else it wouldn't be blind )

Thank you (and Tyll) for pointing me towards a really great hour
