Is decoupling nescessary for REHEARSAL rooms?

Hi, i'm considering (planning) starting a rehearsal rooms business, and I'm basically wondering if full studio standard isloation is nescessary, as no recording will be taking place in the rooms. I was planning on contructing the rooms with the 'room within a room' design, apart from the floor, as floating the floors would be too expensive. But then I was thinking that I could just beef up any existing rooms, and/or build new rooms that would be in contact with the existing structure. I would be using timber partitions with double layers of plasterboard, and rockwool etc. But would you think that total isolation is needed or not? Thanks a million, Barry.

Funny how I was able to quickly locate this particular needle in the haystack of this forum -- I happened to remember the word "confusion" that Steve emphasized in his response, so I just searched for all posts by "knightfly" including the word "confusion." :mrgreen: Anyway, there's your answer: investing in room-to-room isolation is good, even if only for rehearsal purposes.

Thanks Keith, couldna sed it betur meself... :mrgreen:

The rooms themselves would be decoupled from each other, thats a given. What i'm wondering about is decoupling from the actual shell structure of the building. i.e. if I build a fully decoupled room (room within a room), would that be hugely more effective than if I used an existing wall or two and then just section it off with framing, insulation and plasterboard?

I've attached a VERY basic drawing to try and illustrate what I mean! I've never used Smartdraw before! Which of the two shown would be better, bearing in mind that the second would cost roughly half as much as the first!

Barry, this http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3231 Is there for a good reason; following ALL the bold points will answer most of your questions... Steve
