bass and drum - blocking
« on: October 30, 2012, 07:42:33 PM »
Recently, a contractor converted office space into rehearsal studio space.  Each studio has 2 layers of 5/8 fire rate dry with green glue between the drywall.   Between each studio, there are the drywall layers in each studio and the wall space between is filled with fiberglass insutlation.  The walls go to the deck (the roof) with acoustic caulking along the edge between the wall and the deck.  The deck is metal/tin, with glue/tar/sheeting on the top of the roof.  The acoustic caulking was used in the corners and base of the walls.

Note: tearing everything apart to add isolation between walls is not an option, to sound blocking seems to be my only option available.

As an experiment, I used 1" foam mat and attached it to the inside of a door, and made 1 foot wide strips of the foam mat and attached it to the corners adjoining the next studio/room.  The corners ran from the floor to the acousting ceiling tiles and not to the deck/roof.

The bass and drum sounds were decreased a lot (a lot).  With the success, I plan to do more.  I plan to run 1' to 1.5' wide strips along the wall corners all the way up to the deck, and I will also add strips where the wall meets the deck, and possibly where the wall meets the floor (along the baseboard). 

Which material should I use?  I had success with 1" foam mat, but would 1/2" suffice?  Should I use MLV or double weight MLV instead?  What about the MLV/open cell foam?

I will make my purchasing decision after your response.

Thanks, Jimmy

If you had success with 1" foam mat than I would recommend thicker and more coverage as opposed to reducing the thickness.
Try 1 1/2" ...remember low frequency is the hardest to reduce..

Ok.  I priced the foam mat that I think need... and the total to came about $1800, which is fine.  However, the shipping was about $750, which is not fine.  Do you have any suggestions on an option that would not cost so much to ship?
