Which is the better layout?

Hello Forum, hello Kendale, Aaronw and John This forum is great. Thanks to anyone who works on it. Could someone pls help me with the following? I want to convert a room (6.7m x 15m x 3.5m WxLxH) into rooms that will be used as - rehearsal room (loud band, 4-5 people) - project recording studio (CD Pre-Productions, Soundtracks for Multimedia, Theater and Exhibitions) I want four rooms: A) Control Room, B) Studio, C) Kitchen, D) Storage. Height of the new rooms: 2.40m The Studio-Room is build in the room-in-room manner with a TL of approx. 52db Now I'm trying to workout a good layout for the rooms. My question: :?: which of the following layouts would be the best under an acoustic point of view and under a "working conditions" point of view? Thank you for any help on this!!!

Hi Giancarlo, There is an announcement at the top of the forum about what to do to assure getting as many responses as possible. The announcement leads to this post (click here). Actually, several people, who are experts on this forum, will most likely not reply if you don't do what is written in that post. Many others who are very helpful, will most likely not reply out of respect for the moderators' wishes. In any event, none of your proposed layouts makes sense acoustically, mainly because of the shape / size / layout of the control room. There are some basic guidelines for control rooms, and all four of your layouts do not follow them. To start with, you need symmetry. The control room should be symmetric. None of yours are symmetric. You also want the control room to widen out from the front. None of yours do. You should also have the room deeper than it is wide, but all of your proposals are wider than deep. Also, both your control room and your live room ("Studio") need to be properly isolated. In your layouts, the control room is not isolated at all, and it also looks like your live room inner-leaf is coupled to the building outer leaf, in several places. Finally, there are certain places inside the control room where certain acoustic treatments work best, but in all of your diagrams you have those places occupied with other things. I'd suggest that you look around the forum for designs that are close to what you need and might fit your space, then modify them a bit until they fit. - Stuart -

Hello forum, hello Soundman2020 First of all, sorry about that. I wasn't aware to offend any forum rules. I did read that specific post but maybe didn't understand properly. Nevertheless your answer already helped me a lot. Thanks for pointing out to me these important facts about symmetry. Believe me, I've done a lot of reading in this and other forums before drawing the layouts, but somehow I didn't get the point. I was just concentrated on avoiding parallel walls. Maybe I learn better when I'm told what not to do rather than what should be done. I tried out your suggestions today and designed different variations of symmetric control rooms into the existing location and then added the other rooms. I found this solution here works best for me. What do you think of it? :?: Like the layouts I posted yesterday, this is only a rough sketch that doesn't represent the construction details nore any acoustic treatment inside the rooms. In the end the rooms will be isulated and of course separated from the outer hull. I shoud have mentioned this in the former post. I was thinking of measuring the rooms when the inner hulls are built to define what kind of treatment they would need inside.
