Hello,
I'm thinking of building an acoustic cabin, designed to work as a "small show room" for the PVC doors and windows that my company works with. I'll be using just a PVC door with triple insulated glass as entry, so the rest will be made of solid material, It will measure and somehow look like a telephone cabin *but with glass only in one side:
I really need to be able to forklift it and carry around expos, probably concede as a "cellphone room" on certain events, so I'm thinking about 4 massive rubber stands on the corners, they'll also help to isolate vibrations from the ground.
Now, about the walls, do you think that using 2 nylon (or similar) sheets of 1' sandwiched with sound dampening foam would be enough for the walls, or would you suggest another material? It would end up like a dense rubber room inside a dense rubber room, with acoustic foam in the middle..

If I build this you bet I'll post pictures and the results
