Building a Studio

Post by Xspringe »

Hello everyone :)

I'm currently working on a project studio which is to be built inside a hangar: http://www.dikkechill.com/xspringe/area.gif. The Red line indicates the are where I would like to locate the control room, the dimensions are shown in millimeters. As for now I am focusing on the production/control area, with a possible future addition of a recording area.

The location is fairly quiet, the hangar is constructed out of concrete, and therefore isolation is not of enormous concern (for now). I will be using a dual layer of wood and rockwool (room within room principle) which according to manufacterer specs will deliver about 55 db isolation (STC).
As for now I am concentrating on the shape of the room, accoustical treatments are of later concern.

So far I have come up with the following plans:
Side view: http://www.dikkechill.com/xspringe/zij.gif.
Top view: http://www.dikkechill.com/xspringe/boven.gif.

I'm taking the LEDE approach, and I thought I had things pretty much nailed down but I ran into a few problems recently:
- Because the room isn't entirely rectangular I have no way to calculate room modes properly.
- Some people have been saying that splaying walls about 10 degrees should help prevent flutter echos, others say it makes the room too unpredictable
- I'm having doubts that the room length of 5.10 is enough to create a proper initial time delay of 20ms+ (current calculations indicate a worst case scenario of slightly over 20ms, but I'd rather have a larger margin).
- Some information suggests that nearfields are unsuitable to be soffit mounted and a different approach should be taken.

If anyone is able to help me solve these issues, or happens to have a good studio design laying around which fits within the specified dimension limits, I would be delighted to accept their help.

Hi Alex - firstly I'd look at orientating your control room so the 7m length becomes the length of the control room. Splaying the walls is part of the soffit mount geometry. Do a search on soffit mount on this site and you'll see what I maen.

Yes I understand that (check my plans ;), all early reflections except the ones reflecting via the floor have been taken into account. The question is whether I should angle the entire wall or only the front part, and how one calculates room modes in case of angled walls in general.

Thanks for your suggestions though.

Also I'd love to know if someone has built a control room that the person felt is very good and fits within those dimensions.
