Building studio from ground up...tips

[jinglesmountjoy]

OK, since this would be my first post, I'll say hi to everyone.

I'm building my studio from scratch and have decided to put it in my garage (a 9'x14' corner of my garage).  My needs will likely be different than most of the posters here on this site as I'll be using it for voice-over work only (commercial reads, e-books..etc). 

The problem is, I have very little experience in acoustics and soundproofing and from what I've gathered on the net thus far, I've decided to build the 9x14 room of standard 2x4 with Roxul insulation, and standard drywall.  Within that room, I'll then construct a 'mic' room using the same 2x4 wall construction and insulation but this time, using QuietRock drywall (each sheet equal to 8 regular drywall sheets).  The 'mic' room will also contain no 90 degree angles and will be lined with something other than paint (ie. foam, carpet, sleeping bags, etc).

Before I jump in... I was hoping to get some tip from people who've had a lot more experience with these things considering that I need this for professional recording.  I should mention that I'm trying to keep sound out rather than in and the loudest noises I have to deal with would be the odd ATV/Snowmobile, schoolbus, Harley driving down my street.

Thanks in advance.

I should also mention that the methods I mentioned above are in no way, set in stone.  I am open to any and all suggestions

Welcome to the board. Glad to have you here.

There are two things to consider about sound control. Keeping sound from going through the walls like you mentioned. And the other is controlling reflections inside the room. That is the part that usually effects our recordings the most and gets neglected the most. Again go to this site, http://www.realtraps.com watch the acoustic videos, and read about the testing they have done. You will learn a lot about reflections and absorptions.

There are other good links to acoustic sites here too.

Hope this helps.

Hi,
This would probably be a good addition to your recording room and I found this coupon on Sound on Sounds website and i thought i'd share it as its only valid for 6 more days, means your can get 50% off!!!
You can get a Vocal Booth 'Home' Edition for £67.50 (Usually £134)
There is 30% off on the site due do some sort of summer sale, then this coupon gives you an extra 25% on top, seems a bit silly to me, so might be a fault, but once you've brought there's not really much they can do, cause of trading standards!!
Coupon Code: HOMEBOOTHDIS124
