(sorry if this is duplicated - it gave me an error on the first attempt)
I am going to be using a 9 x 13 room for an office and am trying to reduce the sound coming in.
Two walls (north and west) are concrete blocks and brick with two small windows and I am satisfied with the noise level coming in from there.
South and East Walls are currently 2x4 studs insulated with 5/8" drywall. The South wall is against the stairwell (and laundry room) so I am PLANNING on adding a double wall to reduce the vibration from the stairwell. I don't know what i am supposed to put between the two walls - air or other?
Here's the plan - please let me know if there are any better options (around the same price range) ...
--outside of office-----------------------------------------------
existing: stairwell
existing: 2x4 studs (w/fiberglass insulation)
existing: 5/8" drywall
<< 
some sort of air gap or other???>>5/8" drywall
2x4 studs (w/fiberglass insulation)
5/8" drywall
--inside of office-----------------------------------------------
additionally the noise from upstairs on the hardwood floors is loud.. so i am PLANNING on the following - let me know if there are better options (around the same price range):
--upstairs of office-----------------------------------------------
existing: oak hardwood flooring
existing: tongue/groove underlayment
existing: floor joists
SSP channel mounts
DWFC
1 7/16" green tape
5/8" drywall
--inside of office-----------------------------------------------
Any advice is helpful as i would like to place my order for materials this week (hopefully).
thanks!
