Working backwards 1,3 for the hallway would meet the standards in Canada and USA for handicapped acces in buildings. That is good, maybe. I do not know what Spanish standards are. For the recording space, if you can fit a drum kit in there, and your drawings show that, it will work. It will be quie intimate, but usable.

Can i build a nice 40m2 surround studio?!

Great :). what's the tips for the walls? i did some tests and i have arround 70db of noise in the studio spot (without walls) . maybe it can go to 80 maximum. what kind of materials and isolation do you recommend??
thanks
cheers
What is normal construction in your area? I sem to recall concrete block walls are normal. They would be great!
Andre
yes definitly the exterior walls will be concrete but i mean inside. I think "after" the concrete this is a good idea for isolation. and than some badpanels like in the foto for all walls (the rear wall will have a difusor)What is normal construction in your area?

Hi guys
Before I go any further i would like to hear your opinion on the framing that I'm planing for the walls.
thanks

What is your budget? Those panels and systems are expensive. You balked at an additional door because of cost. That is minimal compared to cost of using the systems you posted.

Where is your speaker alignment circle? What are control room wall angles based on? What is purpose of the angle on the hallway/live room? AndreBefore I go any further i would like to hear your opinion on the framing that I'm planing for the walls.
I have a small budget. i made a simulation for the cost of these materials and yes its kind of expensive. so i though something else that i will show u in the photo below.What is your budget?

I thought I might not insert the speakers in the walls because if in the future i hope I'll have more budget to upgrade them. For the wall angles i need some help in that. i just draw them not to be parallel and not to steal a lot of space. but i see for your answer that they are not well planed. Thats why i did that corner in the hallway/live room, to loose that parallelism. thanks a lot for your help... TattaWhere is your speaker alignment circle? What are control room wall angles based on?

I wrote nothing about flush mounting the speakers. :shock: My question is where you are going to locate the speakers and the listenng position. Regarding flush mounting, there are numerous advantageous to it. You can use Barefoot's flussh mount which is easily upgradeable to different speakers. The wall construction method you posted looks fine as a general method, but. You do not need double gypsum on the inside of your outside walls, and and inside walls do not have any concrete block. Remember my signature line... AndreI thought I might not insert the speakers in the walls because if in the future i hope I'll have more budget to upgrade them
sorry about that. here's the picture with the speakers location.My question is where you are going to locate the speakers and the listenng position.
The concrete that i signed there is the exterior wall. The double sheetrock was to be able to put some "tar panel" (sorry i don't know how is it called in English in Spanish is "lamina asfaltica") to have more exterior isolation. and then apply some acoustic panels in the sheetrock. i might finish the walls parallels with the sheerlock and maybe after it I'll apply some acoustic panels to loose the parallelism?!?!The wall construction method you posted looks fine as a general method, but. You do not need double gypsum on the inside of your outside walls, and and inside walls do not have any concrete block.
here's the picture with the speakers location.[/quote] You can make you speaker circle larger. The "sides" of the circle are imaginary. Make it so large that the rear speakers are against the wall.
The construction with a single layer of sheetrock is good for your application.The concrete that i signed there is the exterior wall. The double sheetrock was to be able to put some "tar panel" (sorry i don't know how is it called in English in Spanish is "lamina asfaltica") to have more exterior isolation.
Please explain what that has to do with a double layer of shhetrock.and then apply some acoustic panels in the sheetrock.
? Andrei might finish the walls parallels with the sheerlock and maybe after it I'll apply some acoustic panels to loose the parallelism?!?!
I understand but right rear speaker will interfeer with the entrance door.You can make you speaker circle larger. The "sides" of the circle are imaginary. Make it so large that the rear speakers are against the wall.
I made some db tests and i have arround 70 to 80db of exterior noise that i need to isolate.The construction with a single layer of sheetrock is good for your application.
That has nothing to do with the sheetrock (sheetrock it's the same as plasterboard right?!). The sheetrock double layer is exclusive for db exterior attenuation.and then apply some acoustic panels in the sheetrock. Please explain what that has to do with a double layer of shhetrock.
What i meant was to build the main walls parallels and cover them with acoustic panels and difusors with an angle so that the parallelism is "lost" and i can eliminate the early reflections. i hope my english doesnt sound very chinese. :mrgreen: thanks 4 ur helpi might finish the walls parallels with the sheerlock and maybe after it I'll apply some acoustic panels to loose the parallelism?!?!
What is your rear speaker angle? The EBU spec is 110 degrees plus or minus 10 degreesI understand but right rear speaker will interfeer with the entrance door.You can make you speaker circle larger.

You already wrote what the outside sound levels are. That is what I am working with. The construction with a single layer of sheetrock and concrete block is good for your application.I made some db tests and i have arround 70 to 80db of exterior noise that i need to isolate.
Why are you worried about parallel walls? AndreThe double drywall IS NOT NEEDED for that sound level isolation.What i meant was to build the main walls parallels and cover them with acoustic panels and difusors with an angle so that the parallelism is "lost" and i can eliminate the early reflections.
in the drawing is 150º and in the doc that you sent me its says the optimum is 135º to 150º. Should i go 110º?What is your rear speaker angle? The EBU spec is 110 degrees plus or minus 10 degrees
But maintaining the wood stud framing with rock wool no!?You already wrote what the outside sound levels are. That is what I am working with. The construction with a single layer of sheetrock and concrete block is good for your application.
shouldn't i be for acoustic treatment, to avoid echoes etc? the recomended ratios for my control room are: 1 : 1.14 : 1.39 1 : 1.26 : 1.59 1 : 1.28 : 1.54 1 : 1.30 : 1.90 ... thanksWhy are you worried about parallel walls?
If you want recomemded ratios by the latest theory, look at this spreadsheet from the third page of this thread. Andre EDITED to correct markup errors.in the drawing is 150º and in the doc that you sent me its says the optimum is 135º to 150º. Should i go 110º? Why are you not reading the documents? This is your studio. The more you know, the better it wil be. I have linked three documents. Two of them specify 110° nominal. Only the NARAS doc does not. The other two are international formally recognized recommendations. A fourth document that recoommends 110° is EBU Tech 3276 Supplement 1.Yes.But maintaining the wood stud framing with rock wool no!?You already wrote what the outside sound levels are.

With rectangular spaces, splaying can loose floor area. In many cases the area is not lost because of bass trapping in the walls, but you will have fantastic bass absorption in your ceiling.shouldn't i be for acoustic treatment, to avoid echoes etc?Why are you worried about parallel walls?the recomended ratios for my control room are: 1 : 1.14 : 1.39 1 : 1.26 : 1.59 1 : 1.28 : 1.54 1 : 1.30 : 1.90
Sorry. I thought it was universal and that The National Academy of Recording doc was "the recommendation"in the drawing is 150º and in the doc that you sent me its says the optimum is 135º to 150º.

I'm confused. Some says it's good to have rectangular room and parallel walls. some say it's not... :shock: In this last threat u sent me according to orangenumerik the best way is to find an wall angle between 12º and 30º. I saw some big studios with angles only till the early reflections and cealing, and with basstraps in the rear wall. is this a way to go? thanks 4 u timeWhy are you worried about parallel walls?
Orangenumerik is not an expert. Read Eric Desart's response. He IS an expert by any way shape or form. AndreI'm confused.
