Question about side walls

(5 minutes and 4 seconds too slow!!! Damn!! I have GOT to type faster, if i ever plan to beat Andre.... :) )

haha, Thanks! So taking in consideration what Andre said, in the case of an Inside Out wall, The Hard surface wouldn't be the one you "see" either the drywall placed behind the insulation ? (in case there are no slants on top of the insulation)

Andre and I are saying the same thing: The surface of the inner leaf that faces the room is what we are talking about, and that is always a hard surface (drywall, brick, concrete, wood, glass, etc.) That's what you measure to. If you have insulation in the room, then that is part of the treatment, not the construction. Slats are treatment, not construction. Slats are not part of the inner leaf. So you should NOT consider slats, insulation, bass traps, panels, diffusers, furniture, clouds, or anything else that isn't part of the actual inner leaf construction. You ONLY consider the hard inner surface of the inner leaf, regardless of what is supporting it. Nothing else. It is the hard inner leaf surfaces that define the basic room characteristics (such as modes, resonance, etc.), not the stuff that you add afterwards. In other words, what Andre said also holds true for inside-out walls: it is the hard surface that you see on the other side of the studs. - Stuart -

Thanks for clarifying about the slats. And for the Inside Out question that was exactly what I was meaning, maybe just my English limitations didn't helped to make clear my statement. Thanks!

I thought that was what was trying to be prevented here...that it is a race?

Is a soffit wall considered a hard surface too? ;)

You are not going to like the answer. If the wall is a hard surface, then yes. Andre

On the contrary ;)
