Control Room Design

tgauge · **Posted:** Sun Dec 14, 2008 8:47 am

Hi Guys,
I posted my first post several days ago with all of the pertinent data in it here.

I have updated my design and built a 3-D Model.

Am I on the right track? What would you do different?

Looks good but, how big is it?
HxWxL
Where is it?
What are you trying to achieve?

Hey, sorry, looks like exported without the measurements on...

The total interior room size is 18'6"w x 19'6"l x 9'6" h...

I'm designing a garage conversion for the home that i am closing on tuesday. I posted the whole full of detail post here (viewtopic.php?f=1&t=11483) but didn't really get a response.

I'm already re-thinking the design though. I really wanted just to be able to have a great control room for mixing and mastering with the ability to do overdubs and some vocals but now i'm thinking i may redesign and try to add a place to record drums. I just think that's it would prove to be a better return on my investment if i could skip going to the studio where i work and paying the freelance fees and just record drums all at the same place.

This is what i'm thinking of going with instead of the large CR this way i have a decent amount of space for a drummer if need be.

It is a better usage of space.
I would angle the wall between the vox booth and drum room a bit more. It might aid in the sight lines from the control room and make the vox booth a little lest square.

Hang on what about the wifie! No storage in this design? :wink:

tgauge · **Posted:** Wed Dec 17, 2008 8:13 am

Ahhh, you noticed, i didn't mention that i got the permission to use the entire garage. I'd like to keep some storage for things like guitar cases, blank media, etc. but it's not my top priority.

I actually closed on the house today so i'm hoping to have the framing started by the end of january. I'm excited.

Here's the slightly updated version of this design (been busy to work on it).

My main question is: do you feel i'm utilizing the space for what i want to accomplish in this area?

Second question: i'm coming up on the searches with mixed answers to the roof=a leaf question. If you have Roof + Air + Drywall does this count as two separate leaves even though the roof is not airtight. I want to add an additional ceiling on each of my finished rooms which would make my scenario Roof + Air + Mass + Air + Mass. Logically the roof would be mass but it's not airtight so i can't rely on it to help reduce sound transmission. What is the lesser of two evils? Can someone point me to a discussion with the right answer or spell it out for me?

Yes. Read the link for an experiment you can repeat yourself if you wish to confirm that airtightness is not necessary for a leaf for MAM resonance to occur.

Thank you Andre...
I read that experiment. I understand now that it doesn't have to be airtight to become and "amplifier" if you will.

So does this sound like the best answer to my common scenario? Am i getting it?

tear out the existing drywall ceiling, use it to build up the mass on the roof, hang bass hangers in a dense pattern from the exposed rafters, build my rooms with independent ceiling, and then just pray the neighbors don't get upset about the gorilla in the tracking room?
this would give me a two leaf system with an unsealed outer leaf.

another words:

this is what i have:

Close. In case it has not become obvious, seal the roof. Use sound baffling ducts for required ventilation in the space.

Then you can scratch the praying for understanding from the neighbours.

Thank you again Andre!!!

On this topic... The garage door... I want to leave the door but take down the mechanics of it. No big deal. Leaving it on though means that unless i attach something directly to it to make a single mass out of the door then it will become the dreaded third leaf. I've read several people on here talking about building a frame inside of the wall cavity, affixing a 6-8mil barrier and filling the space with a dense filler so that it would act as a single leaf.

Is this the best answer if i want to leave up the door? I know the best would be to take the door down and build a solid single leafed wall, but it is a compromise i have to make.

Once i figure this out i have got a great understanding of where to start on the shell of the garage and can start focusing on the inner rooms.

Yes it is. Keep the space between the door and the new wall as small as possible. Before starting the filler wall, stop all vibrations/rattles in the door.

I can't say thank you enough for your time... This forum is a goldmine of information.

What are the consequences of soffit mounting my two nearfields and then deciding to switch over to a 5.1 system? If the other monitors are not soffit mounted is it going to cause problems?

You may want to visit this link to understand better what this ventilation system does and some of the pitfalls surrounding modifications:

It is not going to be as easy as it may at first glance be.

It will be terrible in LCR matching. If you are seriously considering surround in the future, which I highly recommend if you are considering going commercial with the studio or your work, make arrangements for flush mounting the centre channel also in the future.

The norm these days is for the rears to have different acoustics around them to be quite acceptable. Plan your monitoring circle appropriately.
