Anyone Ever Soundproof A Garage?

Postby Guest » Wed Jun 26, 2019 12:50 pm

I'm in the planning phase of getting ready to build a rehearsal room in my garage. My plan is to use one corner of a 3 car garage with a room within a room construction for a 13×11 room with a 9-foot ceiling. I've read the applicable chapters of Rod Gervais' book, but still have some questions which may be some of you with practical experience in this area might be able to answer.

First, the floor- it is a concrete slab and for best possible isolation you want to build an isolated slab. I'm not prepared to bust up the floor and pour a new pad though, so I'm wondering if rubber mats and linoleum would be a good idea for the floor of my room. Rod Gervais claims that building a floating wood deck on top of a concrete slab does nothing to increase isolation because the deck will resonate like a drum head. Will rubber and linoleum help or will it just amount to throwing money out the window with no appreciable gain in sound reduction?

Next, the existing ceiling and walls are finished. I plan on integrating the ceiling and the two walls which make up the corner of my garage into the structure for my outer room. I was thinking that I would add 2 layers of 5/8 gyprock to the existing surfaces then add sound batt insulation. I would tie in the other two walls to the existing walls and ceiling, adding 3 layers of 5/8 gyprock to the exterior of the walls with sound batt insulation between the 2×4 studs. Inside this, I would leave a 1" air gap and then frame up the inner walls and ceiling with sound batt insulation inside the studs/joists with 3 layers of 5/8 gyprock on the interiors of the walls and ceiling. The inner walls would be isolated from the concrete slab using foam strips. Does this sound adequate to contain the sound of a drum kit?

Lastly, I'm planning on adding air exchange by way of two vents with sound baffles over them with a bathroom exhaust fan added to one of the vents. The baffles will be MDF boxes lined with mineral wool, constructed so that air/sound will have to pass through several chambers before exiting. Would the use of such a system constitute a "short" which would negate the effectiveness of my wall construction? Apparently, soundproofing is only as good as it's the weakest link, so I wouldn't want to throw a lot of money and time into my wall and ceiling construction only to have the ventilation negate it all.

Another spammer.

http://www.drummerworld.com/forums/index.php?threads/anyone-ever-soundproof-a-garage.127328/page-2. I think that this itself was lifted from another forum going back to 2009.

What do these people think that they are achieving?

Rubber mats (like in a gym) work great. The floor is the least of your worries.

Steel studs will transfer less vibration than wood because they are so thin. I'd suggest soundboard type sheeting, then drywall. You want to create a vibration damper and softer, more porous material will dampen better than sheetrock. Two layers of sheetrock will be dense and transmit the sound. :protest: Spammers of the world unite. :protest:

Thanks, good spot. He’s banned, but I have left the post as there have been replies.
