Dead ceiling...WAF

[abefroeman]

What do you guys think about going for a totally dead ceiling with some OC 703? Just keep it really simple and glue some white batting to bunch of OC 703 and layer them onto the ceiling. Not sure how they would stay up, but those are just details. Just make it 4" thick over most of the ceiling. What do you guys think?

I like the high WAF and it seems to be pretty cheap.

Yes I know about first and second reflections and stuff but it can't be too bad to go recording studio style in places where you can't put treatments in the first reflections.

Isn't that product 1" thick? How would you go about making it 4" thick?

"Totally dead" is a near impossiblity in real life habitats...outside of anechoic chambers. It may be nearly nil as far as reflections...but. Some resonance is a good thing, and most reflections, for that matter (after the first) are typically not so bad in a well-designed theater (you write you are already aware of reflections).

That being said, are you trying to soundproof the floor above, or make your room (you didn't write if it was a theater, listening room...) less reflective? Typically walls are the biggest culprit (provided you have some carpeting, some door and window treatments, and do not have a stainless steel ceiling).

When I changed one of my rooms to a HTR I ran into acoustical problems with alot of reflection. The room was all paneling with a concrete floor. I was thinking of the same thing as you are but a friend said I should start slow so I built a couple of bass traps and two panels to hang on the walls and it made a huge difference without alot of time or money.I guess what I am saying is don't go crazy, you will be amazed at what just a fairly small change and some calibration will do.

good advise

Treating a room properly is a carefully considered exercise in compromise and completeness. If you have carpet on the floor, no way would I kill the whole ceiling. If you have a hardwood floor, then an area rug between you and the speakers and a 'cloud' of sorts would be appropriate.

If you want to dress it up, make a nice wood frame (stainable), fill with absorbiton, and let the cloth show through the wood frame. Use some cross members to make it look like a coffered ceiling. For an added touch if you have 110v up there, try some rope light just inside the perimeter to uplight the ceiling with the rest of the lights off for a nice touch.
