Hello everyone. Here is the SmartDraw version of what I am working on. I couldn't find those nifty CR graphics that everyone uses, but here it the rough drawing. I am building a Control/project room. This is going to be 95% personal use so I want to be able to do things all in one room. I also would like as good a "listening room" as possible. Some points:
The Slab dimentions are 16'x22'
The workshop (the room with the desks, etc) is framed with 2x6.
The studio is framed with 2x4 with the intention of doing a "room within a room" with 2x4's. the dividing wall is 2x4. The studio dimentions are 16'x11'x10. This can and will be changed with internal 2x4 walls.
The ceilings are 10' tall. it is currently framed, with OSB on the exterior, with plans of plaster exterior. Metal roof. I have 18' trusses on the roof on 24" center. There is not yet any ceiling. The trusses are 10" deep. There is not yet any internal drywall, etc.
I was originally thinking I would have the control room facing towards the workshop, but then I have seen that here most of the designs have the CR facing parallel with the longest side of the room. Unfortunately, my room doesn't match the whole BBC 1500 cubic feet thing, but I want to do the best I can with the space.
It is possible to move the door of the seperating wall if I need to even though I have already framed it.
What do you guys think? I'll be happy to post photos If people would like.
The workshop will only be used by me, so I don't need to worry about isolation from that room.
Thanks for your help!
Joel
I am also interested in seeing a one room design, as my space is only 11"W x 17"L, 8 ft ceilings, with plans for a 4 x 4 vocal booth in the upper right hand corner. Any suggestions?
Joel, you keep talking about the rooms using different terms - do you want to use the upper room in the drawing as a one-room studio, or the lower one, or one as a control room and one as a live room?
Also, do you use part of this space as an actual workshop, or is it possible to use the entire space for music? I'm asking, because the larger the room the easier it is to make it sound good, and the less cramped the feel... Steve
Knightfly,
The upper room will be used as an electronics DIY workshop. The lower room will be used as a control room/project room. The lower room is framed with 2x4's with the expectation of framing interior walls again with 2x4's. The dimentions of the lower room are currently-10'6"'x15'. There is 10' ceiling height. I could possibly move the interior dividing wall one foot to make the control room dimentions 11'6"x15'. When moving the wall, I can also put the door somewhere else within that wall if there will be bass traps where the door currently is. Unfortunately this is less that the BBC's 1500 cubic feet, but I have seen many smaller rooms here, so I don't feel as bad!
My reason for showing the upper room is because I don't need to isolate the dividing wall because I will only use one room at a time.
Joel
If you're only using one room at a time, and things you do in the shop won't contaminate your music gear, how about forgetting the wall and using the entire space for better acoustics? It's not like you're welding, grinding, or cutting plywood, right?
Generally, you can place your mix area at the center of the short wall in a room and place absorbent at first reflection points - beyond that, your 10' ceiling and 15' dimensions are causing some modes to stack up - one way to lessen the negative effect of this would be to build some of John's slant-faced free-standing slot absorbers, shown here - I would change the design to make each section 4' wide, this would combat the 2/3 ratio of height to width more effectively - here's the page -

I'd give serious thought to making this entire space one acoustic entity, unless you've got a bunch of tools on pegboard or something elss that will rattle a lot... Steve
Knightfly,
Thanks very much for your input! Unfortunately (from an acoustics standpoint), the workshop will have wood-cutting, soldering, general mess, etc. For the sake of my studio gear, they can't be all in one big room. I'll read that link and post a new design...
Joel
Bump...It's a shame there are so many of us leechers here wanting knowledge and not many teachers-and the teachers are so busy! I'm thankful for your help and advice. Joel
Probably more like this - you don't want your head centered in any plane other than left/right, or you'll run into serious modal peaks and dips that will help you make crappy mixes - a good front/back head location is around 38% , then make sure your head and speakers are NOT centered height wise either - in an 8 foot ceilinged room, 42" to center of woofers and ears is about as good as you can get... Steve
Oh, I narrowed the speakers because in most cases vertical orientation is better - less stringent horizontal head placement for minimal phasing problems (caused by varying distance of tweet vs woof and your ears)
OK,
I like it. Questions:
1) Do I need to be concerned with more bass trapping (absorption) directly behind the seat on the back wall-or perhaps in the ceiling?
2) How high should the speakers be in 10' ceilings?
3) I can angle the ceiling however I need to. Any suggestions? Thanks!
Joel
1 - likely both - one of John's rear wall traps centered in the back may be enough in addition to the traps shown; if not, the junctions between walls and ceiling near the corners can add more.
2 - 49-52 inches from floor - ears should NOT be within about 2" of 45" - either above or below that distance, and if speakers and ears aren't the same height then speakers should be slanted down accordingly, so they are aimed at the ear level.
3 - ceiling - low in front, high in rear - a steeper angle in the first 1/3 of the front will help first reflections... Steve
I have been working on this and am curious about the angle of the ceiling still. Steve, you said " low in front, high in rear - a steeper angle in the first 1/3 of the front will help first reflections"
Can you give any advice as to specific heights of the ceiling at:
1) The front of the room
2) 1/3 of the way towards the rear
3) the rear
Thanks for spoon feeding this stuff to me. I just want to have good plans before it is built.
Joel
This maybe should now be in the studio construction forum, but it started here, so hoping to finish it in this thread...
...that was my shameless bump.
:roll:
Joel
well, nobody on the board gets paid to be here, so if you want the free advice, you kind of have to work around folks' schedules and whenever they can get time.
Yeah, that's cool.
Is there any specific literature that will discuss the ceiling angles to use? I have the Everet book and I haven't seen it there...
Take care,
Joel
