Needs to be Acoustic Foam (http://www.parts-express.com/pe/showdetl.cfm?partnumber=260-516&source=googleps) and not bed foam. This kind of foam is usually rediculously expensive, but if you look around, you can find it for pretty cheap. Since it will be glued in, it doesn't have to be one large piece. :)

Restriction and disturbance is negligible.

If you don't wish to build your own, Phresh sells the same thing.
