Wall angles

[agent420]

Im rebuilding an old thin wall in my live room and I need some help with the design of the new wall.The material and interior of the wall is not in question.My room is cureently 19' x 15 1/6".The ceilings are acoustic pannels,the carpet is super thick and is parallel to the ceiling.All walls are parrallel.I want to eliminate the right corners on this wall thats being rebuilt at this time.The wall is 15 1/6 adjacent walls are 19' and the opposite parrallel wall is also 15 1/6.
Im planning on doing the same angle to one of the 19' walls which is covered in the center with thick curtains and a solid baffle behind the curtains.
I really would need some help on this design,as im just a student with a project studio.Im just learning acoustics in school.

Ceilings are 8'.This walls is going to be 3/4" drywall layered on 1/2" drywall,fiberglass insultaion in the center,with a layer of gypsum board with an air pocket about 1/4" thick to fill in rest of structure between a fiberboard and a stairwell which is solid wood.One adjacent wall is solid 6" thick,the other is about 4" thick with drywall layered and a foam board inbetween.Theres a double payned glass window in the center of this wall that is 12' X 6 1/2 covered with thick drapery and backed with 1/2 & 3/4" layered plywood barrier with auralex foam covering one side.I dont think theres any other input I can add into this other than this is just the first wall being done,I have added a layer or 2 of thickness to the other walls already but plan on using a few acoustic pannels to angle other walls such as the 2 flat surfaces on both sides of the drapery or the opposing paralell wall.I have rounded moulding up on 2 of the walls.I think its the same moulding that was up prior to me getting in here.Should I go with a triangled moulding thats fat enough to form a 45 degree angle at the top of the wall to the ceiling as a low budget fix?
Im looking into forming the wall at an angle to eliminate the right corners on the sides of the wall and at the eiling so I will need to angle this wall somewhere around 2- 2 1/2 feet up from the floor to yield best results?

any chance of a picture or drawing??

I dont think a drawing is necessary in this case because the room has 4 parallel walls,2 are 16 1/6" and the others are 19'.So its a rectangle right now that can be built in any shape possible fitting the dimensions of 16 1/6" X 19'.Nothing drastic,I just want to improve piece by piece overtime,and I dont have a ton of cash.
Im thinking Im going to start with this wall)16 1/6") by angling it at around 6 degrees.The facing wall may be done at a later time,or even one or both of the adjacent walls,it depends on if Im satisfied with the sound.Right now Id like my reverb time to die alot quicker.Im using a good amount of absorbing materials as I have a 12' wall of curtains,plus a set of thick blanketing I can move around the walls of the room on different hooks.
Im having trouble also figruing out a way to use compression latches on my doors.I have a pocket door that slides on one wall,and another door that opens out of my room on the other side.Outside of this space is all extra rooms for now,my live room is surrounded by empty space.the entry way forms a good sized air lock if I can seal it of a bit with compresson latches.

[John Sayers]

Here's your drawing - is that the door on the left?

Pocket door,left bottom,sliding glass door right center,entre door top right.

[John Sayers]

well give us the measurements then.

agent420 - I'm sorry I really can't understand what you are trying to do here - can anyone else understand this ??

Heres what I want to do,eliminate flutter echo between parallel wall,since all my walls ceiling and floors are parallel...Now,in most every live room ive walked into almost no 2 walls are parallel.I understand the 10-12 degree between 2 walls and all.Im asking about the slope that starts at about 2 ft up from the floor in most live session rooms.
I included the dimensions of the room and the diagram.The diagram is really only illustratiing where the front door and huge sliding window are in my live room since its a rectangle(blank sheet of papper)with only 2 restrictions,the sliding door and front door.The pocket door could be filled up with anything that treated the room.I was thinking of maybe building some type of sofit for the entry door.I have some bookshelfs to put in the room as soon as everything is done.They will be going along the bottom wall in the diagram.The shelves will be angled to eliminate the corners in the back part of the room with an entertainment center in the center of that wall.I may cover that with blankets or whatnot for absorbtion.But I was looking for any possible design tips since nothing has really taken place in the as far as building goes .
I see you guys have alot of fun helping people with the design of the their rooms with your expert advice.If its not fun or you dont feel like helping me thats fine,I came here for any advice I could get on the design of my room from scratch.
Now I raised another question about compression devices to seal a door.Ive heard of compression gaskets,and compression latches,kinda like a freezer door.I was wondering if anyone had any ideas of how to get that type of effect for the doors to my rooms.I cant go buy a freezer type door,so any ideas on that,the compression gaskets may work well for bottom gaps,but Im concerend about the other 3 sides of the door.
Any help would be great,thanks
Best regards,
Sean

I understand the 10-12 degree between 2 walls and all

so what's the problem?? have you searched this site for that kind of info ?? this site is full of it

cheers
john

[agent420]

yes ive searched this site,still cant answer the door question from searching this site,i havent found what I was looking for.Next Ive seen you help people with the shape of the rooms,and what type of absorbers would be best placed in certain areas.
So Ive also asked you another question about the size of the room I may turn into my control room,and whether or not I should use the larger room instead.The room I may convert to a control room is 11' X 16',large room is 16 1/6" X 19'.I would for sure need help making hte room usable if the size isnt prohibiting from suiting a control rooms neds.I had my stereo in there awhile back and the bass really builds up in there.
Anyhow any help from you guys here on this forum would be appreciated n any of those topics.Thanks

Sean - I'm not trying to avoid helping you - it's just that the way you express yourself makes it hard to understand what you are doing - obviously others are having the same problem else they would have answered you also.

OK - what what I understand you wish to make this room your live room and you have another room 11 x 16 for your control room. Where is it??

For your doors check out "Construction" at the SAE site

http://www.saecollege.de/reference_material/index.html

Now what kind of music do you record - do you want a live recording room or dead?? Is the control room on the other side of the window?? if so how do you get there - where is the door??

cheers
John

[agent420]

I mentioned wanting to kill the reverb time alot quicker in the live room,so deaden room.The control room like I said is behind the staircase(staircase in the drawing is represented correctly its just penciled in,though its a 4ft gap between the live room and other room I want to turn into my control room(top left of drawing I sent you after the single room pic 11X16')
My questions are if I should just forget about doing my main mixing in the 11X16' room,and just use it for when Im recording and need to listen,then move my monitors out to the big room?Or if I should go ahead and treat this 11x16' room as a total control room...does it have the space I need for good sound?
And also any treatment and design help you can offer with either room.I record mostly acoustic instruments,though I also record some electric instruments,its mainly acoustic and hip hop stuff going on here.

[John Sayers]

Ok Here is the new pic

Yes - you could treat the 11 x 16 room adequately as a control room - people have treated smaller rooms with success.

My problem is the ergonomics of it all with no visual between the studio and the control room. Why can't you use the room to the left of the live room as the studio??

cheers
john

[agent420]

the room to the left is a kitchen,and I cant monitor in there on speakers without hearing it in the live room,Unless I build myself into a tiny little corner in that room.And I dont want to keep my gear in the kitchen when we are cooking or doing laundry its a pain to vent out the room and run fans all over the place(lol).
I havent been able to see the performer at the mic since I started here,Ive gotten pretty good at knowing when they arent giving me good micvrophone positoning,or if thwey are slightly speaking away from the mic,like intop their sheet music. I may end up with some cheap low resolution security monitor to watch in the room,but the most important thing now is Soundproofing and acoustics.
With the 11X16 room I should be able to keep all my machinjes in the room an monitor pretty loud.Im thinking of building the control room on a floating floor and possibly work on the ceilings.Any room design help on either room would be much appreciated.
Thanks again,
Sean
