Building a 14' x 7' Sound Studio for Under $1,000
« on: February 02, 2011, 10:31:13 PM »
Just built a 14’ x 7’ Sound Studio for practicing and some recording in my 2 car garage…

I am getting ready to paint the inside and outside and thought I would share my experience.  I am not a carpenter or sound pro and this is the first real construction project I have ever done.  This project has taken 60 days and about 100+ hours of my time (at night and on weekends).  It was worth it, but there are a few things I would have done differently.  I consulted with several construction and sound experts about this project, and spent about 4-5 hours of research time online to figure out a general direction.  I also prayed alot during the process because at times it was very frustrating :).  So here is the path I chose and the path I would take in hindsight.

The Path I Chose

The Path I Chose:

2 x 6 staggered studding (actually framed 2 x 4's and then added 2 x 2's after reading up about staggered studding – used as few studs as possible)

5/8 Fireproof Drywall

GE Silicone II between studs and drywall for vibration/shock absorption

GE Silicone II on outer drywall seams and inner drywall seams

Great Stuff for seams too big for silicone (mostly ceiling/wall seams since I had to use irregular ceiling construction due to garage door)

Liquid Nail for footers on garage concrete flooring

The Path I Chose...Continued:

Exterior pre-framed and pre-weatherized steel entry door, 1 dual power outlet not completely sealed to let in fresh air and no windows

Two layers of 30 pound rolled roofing or vinyl flooring (had a few feet left over) on the interior studs between the interior drywall and the studs and on outside roof

Sound deadening board (from Home Depot) between drywall for roof only (roof was very thin overall due to garage door clearance)

Blown cellulose for insulation and some sound dampening

Remnant Carpet and padding at a local carpet store

In testing with a couple of different DB meters it looks as though my construction cuts about 50-60 DB which is what I was hoping for!  Playing music at high levels cannot be heard outside of my garage or inside our house at all which was the ultimate goal in this project.

The Path in Hindsight

The Path in Hindsight:

QuietRock drywall

Acoustic/thermal batting insulation

Standard studding

Silicone for sealing seams only

Axe the rolled roofing

The QuietRock is terrific from everything I have read and would have accomplished the 50-60 DB cut I was going for….If I would have used QuietRock I could have axed the rolled roofing and the silicone on the studs and the staggered studding in my opinion.  I would have used standard batting because the cellulose was a freaking mess in this application and the standard batting would work fine with the QuietRock drywall.

For the investment you have done a good job! After reading your hindsight post, this is where I disagree.
Using quiet rock over 5/8" drywall I doubt it would have allowed you to eliminate some of the important steps you took to accomplish the results you did. It is better than drywall for mass but you would have still needed to decouple.
Staggered studs is always better than standard studding. This is known as decoupling and this process delivers the greatest value.good job!
Agree on the regular batting over blown cellulose.
Sealing the seams was a KEY move! we use acoustical caulk but silicone is better than tape and mud.
for use on the studs was null due to the fact the screws are the path into the structure.we use padding tape for that location and we still have the hard connection. therefore staggered studs delivered the decoupling.

Agree on axing the rolled roofing but it did add some mass but not enough for the time installing it.

You have done a GREAT JOB FOR THE COST!! IMPRESSIVE!

Thank you for your post and I hope all our readers understand that if the main principles are followed you can achieve great results using regular building materials.

1) decouple from the structure or vibrating surfaces.
2) add barrier / mass
3) add absorption
 
You are building a fish tank! therefore sealing the room water/air tight is KEY!..

I bet the new room has a solid/air tight feel when you close the door!

THANK YOU for your post!

Indeed, very air tight feel....And thanks for your comments/reasoning regarding the staggered studding....This was a "slinging mud" type experience for me and I will definitely take what I learned from it, and build an even bigger/better room when I move out of this house. some day.

well feel free to give me a call and we can discuss how other materials will deliver a far more outstanding result...once you have the experience from the first build the next one will be a breeze.!
