2-Rooms Studio help!

Do not do a double ceiling if both are hard surfaces. That can actually increase the issues with isolation.

If you want to spend some time (and money), build the 'real' ceiling at the dimension you've decided on. Then below that, build an angled ceiling (low in front, high in back with at least 1" per foot of taper - more is better) but have the visible ceiling be alternating 4" and 6" slats, 3/4" thick with 1-2" of 703 above it. Gaps to be varying from 1/8" to 1/2". This gives you an angled ceiling in terms of mids and highs and a nice broadband variable slotted Helmholz absorber for bass frequencies as the entire ceiling.

Plywood VS Plasterboard for vocal booth

Great advice bryan really thanks you for your help. I will post some image on my next post for my recent room.

And I also need some advice on vocal booth. The wall of vocal booth should be Plywood or Pasterboard? Which one is better for soundproofing? And are they also acoustically different?

btw I'm really sorry for my too many questions. I can't get any help from my area outside (in my area, I guess 95% of studio won't do correctly and all are very lack in both soundproofing and Acoustic treatments) and more than that, I can't buy any studio design books here. So Sad. So I'm writing here for ur great advice.

Plasterboard is more massive - therefore more isolation friendly. Just be prepared to kill it with a lot of absorbtion in addition to have a nice dry dead booth.

Also, with the way you have it laid out, I'm assuming the entrance to that room is NOT on the front wall of the control room between the speakers - it shouldn't be.

Thanks
In my image, It's my plan for placing acoustic treatments in my control room.
I can't do room-in-room method cos of my budget .
In my image, my CR will be 11.5 x15 x9 and vocal booth will be 11.5 x8 x9.

I know my C.R acoustic treatments are not good enough in that image. My questions are,
1. What should I fill on cement wall in my C.R? Is it enough if I place DIY traps like my image ?
2. For C.R ceiling, should I place acoustic foam at everywhere?
And any suggestions for my plan ?

btw, I didn't make any acoustic in vocal/recording booth. But Im planning to place acoustic foam at every inner surface of booth.

I'd also plan at least a 4'x4'x2" absorber to catch the ceiling reflections and also be over your head.

Concrete does nothing for absorbtion so you'll need more than normal. I'd plan on killing the entire front wall including the door.

For a vocal booth, don't kid yourself. Thin foam will help some but not go anywhere near deep enough for male voices. Male voices can easily extend below 200Hz.

Thanks. I will place an 4'x4'x2" absorber over my head. Only one absorber is enough for CR ceiling? Should I kill entire ceiling?

ok, I'll kill entire front plasterboard wall with 2" foam and then fabric cover it. Is it good? Any suggestions? Do I need to kill entire rear wall and side walls too?

For a vocal booth, don't kid yourself. Thin foam will help some but not go anywhere near deep enough for male voices. Male voices can easily extend below 200Hz.

Thanks in advance. I'll research more about vocal booth.

btw Bryan I have also checked GIK site and I saw a pretty control room on it's homepage with black absorbers on upper parts of front and rear walls.
I would like to know what materials used at the wall surface below and under that black absorbers. In the picture, the surface is yellowish white color.

I would like to know what treatment materials should I use for front plaster wall, entire side cement wall and door. I will show it in my image.
Thanks!
