PLANS FOR ISO BOOTH

Posted: Thu Jul 10, 2008 5:19 pm

I'm closing my project studio for a while and i'm planning on mounting a mixing room and building a little tracking room to continue with some work at home.

I post my plan for mixing room isolation so you can criticise. There are some specific items where i need some help.

*I thought that i could use some decoupling material below the floor to avoid mechanic transmission to the room structure. Maybe some kind of neoprene or rubber pad. Any suggestions.

*I wanted to use something like green glue between drywall sheets but there is no Green Glue in my country. What kind of sealant would do the job?

*I was planning on putting only one layer of double drywall on the walls that limit ith the original masonry walls to avoid triple leaf effect. Am i wright?

*Are metal drywall studs allright? Are there better if they are wooden?

I think it is all for now.

Thank you in advance.

Just a few of my thoughts,

1. With existing floor structure you can't do much to attenuate structural transmission. More mass (MDF) could help, but I'm not sure because it is already placed on „drum head“ floor. If you don't plan to record live drums/300W bass amp there, don't worry.

2. There's no substitute for the Green Glue, don't waste the money. If you can't find GG - do it without it.

3. For the booth, all walls (the ceiling too) should be built as double leaf, as the right wall on your drawing. (the floor plan of whole place should help too... is it the booth inside the control room?)

4. Metal studs are just OK as the wooden.

5. It's common to use fluffy, low density f-glass/m-wool between the wall leaves. Using high density or high compressed fill you risk the structural transmission between the leaves.

Thank you Groff! So you think that even decoupling the MDF floor from the original one won't help? About the left side wall. I would put another layer of drywall but let only 1 air gap between original wall and ne drywall. Am I wright?

The booth would be in a side of the control room. I will be posting the entire plan once i have finished putting details and tags.

Thank you, again. Any other thoughts?

Not much with thin decoupling material and one layer of MDF. I saw Rod's drawing, where the concrete slab is floating on the high density mineral wool, but I can't recall that thread correctly.... I need to check on my hdd.

I'm not sure is it applicable for the booth floor, to use more mass (i.e. sandwich – several drywall layers between two thicker MDF layers) floating on the high density mineral wool.

Besides, are you sure that your exiting floor can take that load? Did you do any calculation of the booth weight?

Yes, you do.
