Quietest lay out order for fiberboard + thick foam
« on: March 08, 2014, 01:21:40 PM »
I want to sound proof door connecting two rooms to block sound coming out of the room where i am putting soundproofing.
Door is regular cheap hollow masonite door 31inch.

Material i have is fiberboard sheet and about 2 inch thick solid foam enough to cover over door with casing.

Looks donэt matter in this case nor i can measure sound outside inside other room anymore.

What will soundproof better:
1. foam first and cover with two layers of fiberboard?
2. put two layers of fiberboard first and cover with foam?
3. put foam in between of fiberboard's like a sandwich?
