Must watch podcast on room treatments

[speakertom]

Audioholics has been doing a series of podcasts on different audio topics. I just watched one on room treatments by Anthony Grimani, the man who is behind the Sonitus USA company that made my room treatments. Even though there were a few technical glitches it was great. He hit all the highpoints of the subject that obviously goes much further. There will be follow on podcasts. It explains how the room relates to human perception and many of the pitfalls in improper room treatments. If you are at all interested in your room, this is a must watch. Here is the link:

This was quite an informative video!

I had a couple of questions after watching it:

1 -- He discusses use of both panels that absorb sound, and diffusing devices that disperse a reflected sound. But I'm not clear what the reflected sound devices do -- why not just use the absorbing panels to reduce the room reflections to an acceptable level?

And 2, he makes the case that some amount of sound reflected from the walls of your listening room is a good thing -- giving you a sense of your own room dimensions.

I'm not sure I understand this idea -- the recording itself will presumably contain reflected sounds from whatever concert hall or recording studio was used in the first place. You'd be hearing this on playback, giving you a sense of the space of that original venue.

Won't adding reflected sound from your listening room interfere with this? You are in effect superimposing two sets of reflections -- original recording venue and your room!

Or to put it another way, why wouldn't trying to eliminated reflected sounds as much as possible from your room, using absorption or other means, be the best way to go?
