Future HT room build- thoughts on my ideas (1 Viewer)

[Steve_Wingman]

I'll start building my basement Ht this fall and so far in the planning I've come up with a room size of 11'w X 21'l X about 7.5h.
Due to soe DWV pipe at the rear wall, I'm thinking about creating a convex curve for this wall for pipe clearance and wondering about sound issues by doing this.
The other thought is with the "long walls" being paralell, I could sheetrock these walls in a "sawtooth" method where as the sheet would be placed standing verticaly on the wall and have the 4' wide sheet angled out by a half inch or a full inch:
......._________________________
....... .......... room front.............|
............................................ /
(hard to draw in asci text)
I would slightly offset the sawtooth placement from one side to the other to avoid having it symetrical.
Any opinions? Is this a waste of time sound wise? The extra construction/ drywall involved is not a issue for me, I have done lots of basements.
Thanks in advance,
Steve.

Interesting idea on the walls, but I can't help you there. I have seen what you mention done in large concert halls in wood or fabric covered soundboard. I have not seen it done in drywall or in such a small space.

My home theater is about the same dimensions as your room. The walls are regular drywall with a pretty heavy orange-peel finish which seems to work quite well at preventing sound problems. A hanging tapestry or two would probably help even more.

Thanks for the response Torgny, I have seen simular wall treatments done in halls also and figure that it's a engineered design to prevent several orders of reflection echos in large halls. But on the smaller scale of TH, I wonder if it will have any effect.
Cheers!
