If I'm drywalling a new room, how much would a 1 1/2" radius bullnose inside corner bead help the acoustics?  The cost of the bead is minimal, and I think the look itself would be pretty cool.  Has anyone tried this?  I've attached a link to the product, No. 7066 about half-way down the page.

For anything under a few kHz, it will do basically nothing.  For higher frequencies, it's actually worse than a square corner as the concave radius will focus sound like a lens.

Thanks, Bryan.  I am going to laminate some 1/4" rock on the front wall (beat-up from wallpaper removal) and thought it might help to get rid of two 90's.
