Low ceiling height

post #1 of 4
Thread Starter 
I'd like to get your advice on my HT. I'm moving everything upstairs to the largest room (still only 13.5' x 18') but my ceiling is very low. It's only 6.5' tall. It is an old farmhouse c. 1800 and the outside walls are plastered stone. Inner walls and ceiling are plaster over lathe.

It's a very messy job BUT I could remove the plaster ceiling getting it down to the joists and undersides of the 3rd level flooring. I would gain 7" total but would still have the 6" tall joists exposed. This all probably sounds nuts but lots of people around here do this just for aesthetics/lighten up the look of an old room. In theory, I could paint the joists and floorboard undersides and even insert sound treatments at strategic spots between the joists to avoid reflections. BTW, the floors are original wide plank hard yellow pine. I'm not concerned about sound traveling through the ceiling into the rest of the house. I AM concerned with in-room acoustics.

This is extreme for sure but if 6.5" plastered ceilings are going to screw me over sonically, I could do this. Any help appreciated.

6-1/2 inches is not enough gain for all that effort, assuming it's as difficult a job as you suggest. Being able to build treatment into the ceiling between the joists is useful, but even when applied to a finished ceiling that will only be two inches lower. And you need to treat only the reflection point areas, not the entire ceiling.

Thank you Ethan. Can you please explain what the sonic advantages and disadvantages are to such a low ceiling in the first place? I will be using a PDP rather than a FP so video doesn't matter as much in that regard. Assuming I will be using absorption and diffusion appropriately throughout the room is the low ceiling a plus, a minus, or neutral?

In general, longer dimensions are better than shorter because of the way room modes work:

Absorption helps reduce these problems because the sound is absorbed rather than reflected back into the room. So a high ceiling is better, but a low ceiling can work fine with absorption there.
