MLV within door systems

I'm considering using Mass Loaded Vinyl 1) as an added layer to studio doors, and 2) between the door jamb cavities in adjacent, free-standing studio rooms.

All of my rooms were built "room within a room" and the doors are doubled (ie, you open a door into your current room and then a second door into the room you wish to enter). The space between the walls/doors is a just few inches deep.

Thoughts and ideas? Thanks!!

MLV is not the appropriate material in doors. If you want to spend money in that range for material use lead or steel. Check the load capacity of the hinges and the frame. After adding material to increase density, the seals become the next weak link.

Having sealed door frames (edges) will have a much greater (read better) effect on the sound proofing than adding mass.

Thanks so much guys - there already are great door seals, 360* around, so we're good.

Because I have extra MLV, I was thinking about attaching to doors on the sides facing inwards....

However, this may not be worth the effort.

How about between the jambs - if you would, covering the void between the double doors?

??? You will couple the 2 leafs, REDUCING sound isolation.

Thanks Andre.

I assumed because the MLV is flexible that it would not couple the two room (like other elastic materials [rubber, etc.]).

I'll stick with fabric between the jamb sets to hide the walls' insides.
