Vocal/Guitar Booth Remodel

[epilogsound]

Hello, I am currently redoing my vocal booth. I have removed a wall between two rooms and made one bigger room. The dimensions of the room right now are 18' L x 7' W x 94" H. I gutted both rooms originally, and I rebuilt the walls using thermafiber between all studs, decoupling channel to hang drywall, and 2 layers of 5/8" drywall staggered with gaps. Joints then had those long strips of foam (can't remember what its called now) and silicon to seal. All walls AND ceilings were done. One of the rooms before merging was at garage level, so we built a 2x4 floor and stuffed with thermafiber since I had some left, and then covered with plywood leveled to the other rooms floor surface and installed floating locking engineered wood flooring.
This is where I am at now. I had previously been using one of the rooms as a small vocal booth. But it was literally square and was not sounding good as a box with all 703 panels covering it for guitars. So I am trying to find the best treatment solution for this size space to record mainly vocals and guitar cabinets. Being able to record a drum kit in there and have it sound decent would be a plus!

I have attached a sketchup drawing that I did awhile back showing the layout of the room. It's been awhile since I used sketchup so I have not done any more design in there. I also attached a photo of the stage it is at right now. You can see skeletal panel walls in the photo that I was planning on putting 703 panels wrapped in fabric in them. I also had enough to do panels above, but was thinking maybe using a different surface like wall paneling or some kind of slat/slot wall? Also in the back of the room where there is a little niche/closet to the left, this space behind the acoustic panels shown, will be for storage, but that acoustic wall was planned to be something that can be moved easily. So one big baffle that can move forward or back.

Thanks, read the READ ME, and I hope I followed the directions ok

*edit The sketchup file was too big to attach here, looking into making that smaller. I attached a screen shot instead

Also was thinking about putting wood paneling above the absorption panel frames shown in the photo. Or maybe even a slat wall type design (vertical or horizontal) above those frames. Having the angle start at the top of the frames (100mm) and then finish going up to the ceiling (300mm).

Or do something like this, which was where I left off years ago. The image attached would actually be reversed with the slat walls being flipped to the opposite side, but same idea.

I had to create a new account here because I could not remember or access my username and pass. But I just found my previous thread which was in Acoustics. Not sure if this is ok being asked here, sorry about that!

Hi there Patrick, and Welcome to the forum!

Sorry about the delay in responding. Busy, busy, busy...

That might not have been such a good idea, as it likely created a resonant cavity under your floor. Fortunately this is just a vocal booth, not an isolation booth for instruments, so hopefully the resonance will be at a frequency below that of the human voice range, where it won't cause problems.

Being able to record a drum kit in there and have it sound decent would be a plus!

With a hollow cavity under the floor, that probably isn't going to work too well. Building a drum riser might help.

If this is going to be a vocal booth, the wall behind the singer needs to be highly absorptive, and the one in front if the singer should add some depth and diffusion to the room. A slat wall would be good for that. The walls to either side could be absorptive, or diffusive, or reflective, depending on the overall needs of the room. Since this is a small room, it would probably be a good idea to make one side wall mostly absorptive and the other part deep absorption and part slot wall, but tuned differently form the front slot wall. The percentage of each (absorption vs. slats) would depend on the balance that the room needs.

The ceiling should be thick absorption, but with angled reflective panels hung a bit below that to keep some life in the room. And the floor could be left bare, hard and reflective.
