Is decent room acoustic treatment possible in a 3x3 space with high ceilings? Regardless, there’s another issue that complicates it (a gap at the top leading to another space)…
I have this very strange, small place to record, and no other options in my house at this time. It’s a narrower-than-usual hallway (I’d say about 3.2 feet wide by maybe 7 or 8 feet long), with 3 doors to/from it, in a 1916 house. Said hallway is sorta divided in half into two necessary “closet” type spaces - so we don’t actually use it as a hallway. The first half of the closet acts as shoe storage accessed by the front entry way, leaving about 3 feet per each side of hallway. So my recording space is only about 3x3’, and has not one but two doors on that side! I enter it from the rear door so that side door just stays shut.
The sound issues and annoying complications are:
-the ceilings are annoyingly high (not sure how high but imagine an old house with typical high ceilings)
-the acoustic quilts (2 plus 1 basic moving quilt) hang from large, long clamps that have upper portions that screw into the wall, but the clamps are long enough that they prevent the quilt from reaching the ceiling if that makes sense due to the way they have to hang. So there’s about 4" of space between the top of quilt and the ceiling, leading to the other half of hallway (other “closet”) that hasn’t been sound-treated and would be costly to treat. Is sound likely getting in/out through that gap?!
-there are two doors to have to sound-dampen, one that’s pointless but there nonetheless. I’ll attempt to treat using weather strip and foam (?).
-there’s decorative horizontal molding that juts out in odd places along the hallway, preventing acoustic quilts from hanging flush against the walls
-and so far only have those quilts for sound dampening, which haven’t worked well enough.
I’m waiting for an order of 12z12 foam tiles (2" thick) to arrive from Amazon in the next day or so (46 or so in all). While the hallway has hardwood floors, I bought a carpet pad and plush carpet and added it to the floor of the recording side.
My questions are:
-Is sound likely getting in/out through that gap?!
-If you suggest that the ceilings are too high and I lower it somehow, HOW ON EARTH would I do that?? Feeling stupid and uncreative.
-Should I put foam on the ceiling then somehow extend it at an angle downward (spray glue or whatever) to fill in that upper gap, or is that single quilt dividing the hallway not enough to block sound from traveling and bouncing off the other side of the hallway regardless of gap?
-Regardless do you think it will help to put foam on the ceiling even with the height and that gap?
-the quilts are so high up that they expose about 1.5 feet of bare wall space at the bottom around the perimeter. I don’t have enough foam to cover every inch of the space much less the entire hallway, so am I correct to assume the most important spaces WITH the quilts, are the lower portions of the walls, the ceiling above the 3x3 space with hopefully something hanging over that gap, the doors, and anything left over be distributed evenly behind the quilts along the walls?
-Or, should I take the extra foam and extend it along the entire hallway ceiling (not covering all of it but some main areas)?
-Is the space/gap BEHIND the hanging quilts (where there ARE walls) a real acoustics problem? Should that be a higher priority?
This was a lot - thank you for your time!!
